There's a lot of girls on the planet, so I'm not going to speculate over the ticklish levels of these two individuals compared to the rest - I'd have no reason to think they are/aren't ticklish regardless of how much I'd like them to be, but...
I would be interested in hearing more on the theory of the lines on the soles indicating ticklishness? Can you illustrate this? I've heard about palm reading and sole reading etc, but never in relation to being ticklish.
Would the same apply to lines on the hands or patterns under the arms etc?
(There is mention of Selena Gomez in the ticklish celebrities section.... I think a magazine feature of quick questions highlighted her feet as being her most ticklish spot, there is a scan of the page out there somewhere).
