I wonder... Do you often say "hello" to people in the street when you walk around?
No? Me neither. But since a few days when I go out, it happens that each time 3, 4 different people tell me hello. //oO\\
People that i've never seen before (!!), and always different ones. Wether I'm on Elzeimer, or there's something I rilly don't get!
