Skateboarding to me is about turning up to a spot and talking about how good someone's style looks, or about about tight someone else's trucks are, or about if I have a lighter, or if my opinion about how well dude A landed his nollie heel fakie on the bank was, or if I know if the shop around the corner is still open and selling sandwiches, or if I know where dude got his board from because it wasn't from the usual shop, or where there's a good party happening tonight, or if the guy stood on the deck has a lighter because some litle bastard stole mine, or if I can have a swig of your water, or if I can ask 'where did you get that board from, I've never seen that before', or 'shit, I think if you move your feet a little bit to the right you'll be able to nail that easy'.
Skatepark banter is brilliant. You might make new friends, or you might find out new things about people you know and love. Skating around with your headphones on not speaking to anyone just gets you a reputation for being a cock around my my way. Just saying.
