This happened long ago so be patient. This occurred when we were both about 14 or 15 and on a church outing. There were about 30 kids our age that went on a trip skating, but we rode the church bus there and back. It was on the trip home that this occurred. It was about 9:30 or so and every one was on the bus just BS-ing when my female friend, I'll call her Liz, started talking to me. She was sitting across the isle from me and after a while she started giving me a hard time about falling. A few more things were said and I decided that I would just get even by tickling her. We've grown up together so this wasn't totally strange. I picked up a foot and took off her tennis shoe and sock and began tickling her foot. She was pretty sensitive at first but kinda got used to it. I eventually ended up with both bare feet in my lap and tickled them for the entire bus ride back, which was about 45 mins. The cool thing was, she said she wasn't ticklish, and for the most part held her ground, but there were spots I would tickle and her feet would twitch or jerk and she would look at me funny and kind of smile. There were other short tickles with her, but this one was by far the best. For those interested, she was about a size 7-7 1/2 with slim feet and long toes, no polish. She and I remain friends to this day, but I'm probably the one who remembers this more fondly!
