I want to make him feel important, and i want to get into topic he likes talking about, which is bikes. I dont want to just sit there saying " uh huh. uh huh. yeah? " , which is kind of dull. All i know is.. that he recently got a Night Train Bike? im not sure if it's mountain bike or BMX, but it's a bike. Lol. So, what should i know about bike to keep up with the conversation?
