I also made an 'excited face' at another stranger because she looked a bit like a friend. It was not my friend. So I badly frightened a woman by randomly 'excited face'ing at her on a staircase and then running away. I have had my eyes tested. It's not that, I'm just dumb.

A more wholesome story. Amber Benson from Buffy once came into the store where I worked in my teens. Again she was super familiar. I thought I’d met her at a party a few weeks earlier. We had a delightful chat then it dawned on me who she was and it was confirmed when she signed her name on the bill

Never apologise! Tell yourself you're the most popular person in the room and everyone wants to meet you. Keep thinking that when you randomly bound up to strangers to say hi :)

I did this with someone in a Waitrose in central London proceeded to have a conversation with the increasingly bemused young man. He escaped at the first opportunity then lady standing nearby told me I’d been talking at Tom Daiey.

I embarrassed myself in front of the YouTube creator @eddache.bsky.social at a comic con. He looked super familiar, but I didn’t recognize him out of context and thought he was someone I knew then he told me who he was and I was mortified! I’m not usually one of those people who bugs celebs.
