Head Trauma

D has just come home and pulled out this long contraption that looks like a whisk with the wires cut at the end. She then commanded me to take my ponytail out and began massaging my head with the ends. OMFG weirdest feeling EVER. Gave goosebumps, and was definitely ticklish. 'It's a BRAIN STIMULIZER!' she exclaimed, and proceeded to repeat the operation on R, who nearly wriggled from his chair onto the floor in discomfort. SO WEIRD, but strangely nice?
Hands up anyone else who has ever had their scalp tickled...
