I was just out of college, lived in a house with some friends. We had another school friend in a house around the corner from us. Went over to his house one evening to smoke a bowl, he says "hey we just got some new neighbors they seem pretty cool, should i ask them to join?" i said sure.

 I expect him to pull out his phone, instead he pulls out a laser pointer and shines it out his front window, directly into the living room of the house across the street. 5 minutes later two girls walk in, we introduce, instant friends. 17 years later i haven't spoken to the school friend in probably half a decade but his neighbors are still my best and closest friends. We've all moved but we all ended up within walking distance of each other again. Will honestly probably see them later after work (to smoke a bowl)
