As much as I love and desire long, drawn-out, intense tickle sessions, there's something incredibly appealing about casual tickling. When I'm lying on the grass outside and the hem of my shirt rides up, and a friend gives my belly a quick tickle... when a friend sneaks up behind me and quickly squeezes my sides or tickles my armpits... when I'm lying on the floor with my bare feet near my friend, who draw on and tickles the bottom of my foot for a couple minutes... it's so silly and playful and fun. It never fails to brighten up my day and make me feel gleeful (and it often leaves me wanting more).
