When I was as student in Berkeley I got probably the most weird comments from strangers of anywhere I have ever lived. Definitely not just men, but I'll stick to men because that is the topic.
I remember sitting outside the post office at Shattuck & Vine waiting for it to open and a strange man came up and said, "Did you use to be a nun?? You look SO serious!" He didn't say it in a playful, flirting way, but more just sheer incredulity that anyone could look serious. I couldn't think of a reply. I just said, "Uhhh..." That somehow prompted him to go on, “You know what you look like? An old painting from like another century of one of those serious looking people they have in museums.” This did nothing to avail me of an answer. It didn’t sound like a compliment so I thought, “Thank you” would be an odd response. I suppose I said something non-committal like, “Oh really?” or, “You don’t say?” He then just wandered off shaking his head.
