My heart jumped into my chest when I saw this. I wont mention anything politics but I will say I like that shes around my age, and DAMN, she's pretty.
I'd kill for a ticklish admission or vid from her. Sounds like this isn't one though unfortunately.
EDIT: Okay so I made this comment before watching the video. After watching it I'm going to say its inconclusive, and really not enough evidence to jump to the conclusion that shes ticklish. Most people would react the same way, ticklish or not, to a dog all up in their face like that. Itd be different if it was lacking her foot or something and there was toe wiggling. Plus she wasn't even laughing or giggling or anything.
It very well may have been a tickliah reaction, but like I said, its not 100% proof either way.
