Aw, heck, I'll go wit' Sydney. Too damned hot out in the bush...
Wait, that wasn't the topic! You tricked me! 😉
Psychological tickling? Jeez, the definition REALLY carries the topic. There's that whole wiggling fingers while sayin', "I'm gonna get you," expecting your "victim" 'lee to start giggling long before you lay finger one on 'em. Then there's the dastardly habit some sinister folks have, verbally teasing someone who's already being tickled, which, somehow, seems to make it SO much worse for the poor 'lee.
Still enjoy the psychology of the play, years later. Yer dustin' off some amusin' oldies, Danimal!
