I was with my uncle once on vacation and we went to an amusement park in Canada you have to take a ferry to get to, awesome place i completely forget the name, but its an island obviously. So here we are, sitting on this ferry waiting for it to take off, some guy sits next to us and i start chatting him up, talking about power rangers or some shit, uncle tells me to leave the guy alone but he just smiles and says its alright, so my uncle goes back to his conversation with his boyfriend about what we are going to do first. Ferry takes off, guy gets up and walks to front of boat, i follow and stand next to him, joking around being a kid. I end up just walking away and going back to my uncle and he says to me "Do you know who that is?" and obviously i didn't so i just say "yea, he said his name was dave" And my uncle laughs and slaps me upside the head and says "no you idiot, thats a stranger, don't walk off with strangers"
