I've talked to him a few times. Once we got into a conversation about tech toys, and I pulled out my Game Boy Advance. He loved it - he said he was saving up for one.
I haven't seen him for a while.
As I write this, he's sitting two seats away from me on the bus. He hasn't noticed me . . . he's playing on his GBA. He's bought the exact same model I have.
Sometimes it's the small things that produce the most happiness.
