The Brixton Hill laughing man

I saw the laughing man this morning as I went to the shop. I used to see him a lot but haven’t seen him for quite a while, though I’ve been away. He’s an old Jamaican guy who is always laughing his head off, muttering something to himself and just laughing. He was walking down St. Saviours Road. I crossed the road to avoid him, fearing that if I got too close I might start laughing as well and not be able to stop.
