Tweak tweak?

I don’t know what reminded me of this, but it was funny. I was leaning against the door in store's main office today, just about to go - when one of my bosses (also a big friend) walks up to me and – tweaks a nipple. Of course i'm wearing a relatively small (ie tight) t-shirt so they were prominent, and so also kind of ‘high profile’. I don’t have to think - i just reach out and tweak back! It was so instinctive, like saying hi.. She wasn’t offended – before anyone thinks that – we’re friends, and plus she’s about the most outspoken and loud person I know – if there’d been anything wrong with it, she would have said. Me, I didn’t mind, thanks for asking!
Anyway, that was a moment of my day. Don’t hate me for it.
btw the picture - it's not me.
