I was mistaken for a man yesterday

[Norse]

I really didn't know how to take that! I've never been mistaken for a man before. So I said "I don't know how to take that - I've never been mistaken for a man before,"

So he said "I think it was your stance. I thought you were a really fit bicycle type guy, then after I passed you I remembered your helmet sitting out on the table and realized it was probably you."

I would take it as a compliment!
