I’ve had this is reverse… I was at work talking to a few people and I feel the hairs on my ankle move so brush my other foot over it, feel in again so brush my foot again. Happened a third time and I’m like this is getting serious so lift my leg up to brush it with my hand and cop a handful of huntsman. It’s about that time I realise someone was watching my foot the whole time and she didn’t say a thing, just let the whole thing play out
