Yes, not surprisingly, the population here is a perilous mine field for ticklish people. I've often thought how vulnerable -- and doomed -- I'd feel if physically surrounded by people from this particular online community.
I would say its normal, if you have had a good tickle and feel very sensitive then for a period you may well be jumpy, even by reading about it or thinging about it, it may well be at the back of your mind and then come to the front once some one is near in a confined space, what is it they say "be careful what you wish for" lol very true on here
