Gothmum .. it must be very interesting for them. My sisters has quite the tattoo collection and dd is totally nuts over it. A while back me and DH got some temp (not yet up to getting ink permentanty) and she is CONSTANTLY asking me to write on her ankle so she can have a tattoo. Even the socks with pictures on it is getting called tattoos.
If she visited her grandpa, she will come home and brag about her tattoos grandpa did on her - hehehe - and at bath time ask DADDY to come and wash it off.
