Say my name, say my name

Why is it so hard for people to remember my name?

In my entire life, I have probably met five other Bonnies, one of whom was my grandmother I was named after. And yet people are constantly blanking on my name, or even forgetting I exist. (That would be you, Women in Mass Comm professor. Every time I'd stay after class to talk to her, she'd look at me like I was a stranger.) Is it because it's not as prevalent people can't remember it? Do people just not even try?

All I know is, this is really becoming a self-esteem killer.
