I have made an effort to take my own advice here and sort of give and take. Some guy, or girl, acting stupidly leeish, playfully insulting me and sticking their tongue out? I chase 'em down and tickle 'em til they uncle out.
I don't always role-play. But when I do, it's with someone I'm a regular with.
Well that's just it. At least in my experience they really don't care that much. They just want to get tickled most of the time. Most will just ignore any signs of a ler wanting to get tickled.
