Thats an interesting response Emma!

Thank you for sharing

Curious, I never thought of fingers as an instrument in the context of tickling () , but I suppose it is. On the hairbrush, I get what you mean, RL usage must trump it right up to the top of the list

it's definitely something that the hairbrush appears to have become a popular choice - from old fashioned nostalgia to first time uses ... you've given us food for thought, thanks Emma
