i must say this sort of thing sounds completely weird to me. i mean, you're only doing it to the odd person who walks past on the street right? if you did it in ED on a saturday afternoon you'd be carted away. i say hello when walking in the woods, but thats because there's no-one else around, if you're doing it on the street why not wave at all the people in cars? thats what makes it feel weird, like you're singling people out, whcih weirds other people out.
