I don’t approach, but I don’t really like being approached, either. I think it’s best to develop friendships first that could lead to something else.
Doing a cold approach would be hard from a social perspective. Being weird and awkward wouldn’t usually work out very well in such a scenario.
I’ve pretty much always had friendships first. I’ve never accepted a date situation from a stranger. They were usually weirdos or, at least, appeared to be.
A weird, quirky friend is cool and interesting, but a weird, quirky stranger could be threatening.
“No, I don’t want to go for a ride with you on your bicycle.” LOL I was 15. Geez!
Good tip: Don’t ask women you don’t know to go for a ride on a one-seater bicycle. (I’m not sure how that would’ve worked. It didn’t have those trick bar things on the back wheels.)
