A friend of mine needed a partner in his doubles junior league. At first I said I'd think about it with every intention of not going, but then decided I'd try it for a few reasons being that A:, bowling has actually run through quite a lot of my family, from my parents through to my cousins & aunts/uncles & B: I needed something to get me out of the house more often, as I had given up being a skate kiddie.
If it wasn't for my friend inviting me, I never would have taken it up. But now I'm glad I decided to go. (It would be interesting actually, going back & seeing what my life would have been like if I didn't go. Completely & utterly different to the point where i can't imagine where I would have been.)
