Same difference

It's crazy i just thought about something. Back in Germany i knew everyone but then again i didn't really. It was just people that i would walked past eeeeveryday. Like when i was walking around in the city. I'd think ' oh yeah it's that guy from the store' or ' the lady that i saw at the doctors'. Here .. new faces everyday. But now i just thought- What if i actually have seen these people? I could be walking past someone that I've been walking past. I've noticed that before. Some stranger randomly came up to me and said " hey , I've seen you a couple times in ---- and -------." i thought about it and well yeah. Sometimes i stare at people without even noticing that i am. So interesting though so watch people, how they act , how they talk. Everybody is so different. Even those people that try to act and be like someone. We are all different. Nobody thinks 100% the same thing you do. It's always a little different. But then alot is the same. Kinda a same difference hahaha. First time i ever used that. My brother says that all the time " Same difference". I'm always like there is no same difference. What's the whole point of the word difference if you put same infront of it.
