Screaming out of cars, cigarette smoke blown in your face, lit cigarettes thrown at you outside pubs, snowballing, gangs blocking the pavement or stepping out in front at the last second, cheeseburgers thrown out of car windows, just a few of the bad ones i can think of. Milder stuff, knees up, who is winning, run forest, can we join you (and some do with beer can and cig much to amusement of chav mates) I find that my dog is a calming presence either people like him or they are afraid - both fine by me.
