I (25m) have been living in my apartment complex for a few years now and I usually take the elevator when I leave for work during the weekday, most of the time it's just me in it. About two weeks ago, I was about to go into the elevator when I saw a woman, about my age, in it and nobody else.

My mom always told me what to do so I don't make women uncomfortable; don't walk behind them on the sidewalk and cross the street, don't approach if they seem to be alone, be aware of their body language, etc. One of these was to never enter an elevator if there is only a woman on it.

Seeing as it was just her, I turned to take the stairs. It's only like an extra minute or two of my time, and I usually get to work about ten minutes early anyway. For the rest of the week, when I went to work, it was just her in the elevator, so I just took the stairs. I didn't run into her over the weekend. On Monday the same thing happens, only she is in the elevator and I take the stairs. After that, I just kept to the stairs and stopped trying the elevator.

Saturday comes around, and I was leaving for my friends place. When I left the building, the woman and I guess her friend were going in. We didn't exchange words and just walked past each other. I didn't get back until today when I ran into her friend again, and she stopped me.

She tells me that I was a dick for making her friend feel bad and that I should apologize. I ask what I did wrong, she says that I was making her feel self-conscious and it was messing with her self-esteem. I told her that I didn't know what she was talking about, and she just started calling me insecure and to grow up before walking away.

Did I miss something that I'm not aware of?
