Why was this lizard and garter snake following me and why were they seeking one anothers company?

For some odd reason and this may sound even a bit strange but why was this garter snake and lizard following me? and I still don't understand what is a lizard and a garter snake doing together? It's like their seeking each other for companionship but here's the story: So i'm walking outside to go and take out the trash and what not as I usually always do and i've came across this garter snake and this lizard which are pretty common here in california and there's a lot of them in my apartment complex but anyway these animals were just seeking each other and these were "wild" animals that live in the wild of civilization, the people who live around are use to the animals but can't remember the name of the species of lizard they're pretty small and grayish, me and my cousins would always catch them in our backyard and feed them to our bearded dragon named "KeKe" when we were little and they still have her to this day and she is very healthy and happy but as I was walking towards the trash can or dumpster that's in our parking lot i've heard a little noise behind me and it was really quiet but I threw the trash away turned around and guess what? yup the snake and lizard were right behind me and i'm not making this up either, they were just staring at me and not in a threatening way and i've tried to not appear as a threat to them and at first after i've turned around and saw them I had turned my head up and tried not to make eye contact with them so they won't feel threaten and kept on walking but they was catching up to me real fast and i've tried to get them away from me and not in my house and believe me I was stuck outside for awhile lol trying to get them away but then i've picked them up and moved them to a further area but not far enough from their territory and ran as fast as I could but they were so fast that they kept catching up to me after every attempt to get them away these animals were very smart but then i've had my sister get a little piece of meat and i've found some insects to give to them to distract them so I could run back in the house but it was not working at all but then finally they took their eyes off of me for a second then I snuck as fast as I can back into my house and made it and then I was looking out my window to come found out that the lizard and garter snake was still there just staring out the door but then i've found this little empty 20 gallon aquarium in my closet and went back out to get them and set them inside and they gave me no problem what so ever, i'm going to release them back soon but for now they'll just stay in the aquarium with the proper lighting/heat source for them to stay warm and a cool side to stay cool and I have a huge water dish for them to drink out of and newspaper as substrate and i've even set them next to my bed so they could see me and I could see them since they were for some reason seeking my company which I still don't understand? but they still seem to be happy and healthy since i've captured them but could somebody please explain to me what was a garter snake and a lizard doing together seeking company? and why were they following me? i'm going to try and post a picture of them and get a video up soon on them before I release them and show you this shocking unusual reptile behavior and i'm going to post it up on youtube so stay tune and my youtube channel is a href="http://www.youtube.com/user/emoneyo2" rel="nofollow"http://www.youtube.com/user/emoneyo2/a but sorry this question was so long but please read it, this is one of my interesting and unusual questions i've ever posted in the reptile/zoology section but could somebody explain this unusual behavior among these two animals that goes against their instincts.
