I'm a boy that's 16. I've always swore that I'm not ticklish, and my mom has never been able to get me. We were all home last night, and she had a friend from work over. My grandma came over too. We were in the living room, and my mom and her friend were talking about kids, and my mom said about me, "Oh, he's not ticklish." It was because her friend mentioned how she's tickled her son. I was standing up, right by where my grandma was sitting in a chair. My grandma looks at me and smiled, ad she goes, 'Hmm.. You're not huh?" And she lifted up her right hand ad starts moving her fingers around, like alternating them around. 1st, 3rd, 2nd, 4th finger, like that. But FAST! And I saw she has nails too! My mom doesn't. I was worried! I looked at how she was alternating her fingers around, and her nails, and I looked at her face. She had a BIG smile. I turned around, and I felt all 5 of her nails SOFTLY, but FAST, alternating like she had showed, right behind my knee, ugh! I was like *GASP* and I tried HARD to ignore it, but the way she moved her fingers around and the touch of her nails made it so I can't! After only like 4 or 5 nails had tickled behind my knee I had to give up, and I cringed really bad and was all "Agggh, ok OK!" My whole knee shook! Dangit! My grandma looks at me and smiled really big, I hated seeing that! I thought I wasn't ticklish, but the way she moved her fingers around ad her nails, awwgh, I CAN'T ignore that! I just walked out, I was pretty embarrassed and humiliated. How can I ignore that when she does that? Is there any way to? She's GOOD at it, and I had to give up fast! Help!
