Does it bother you when people make idle comments about you?

I have a coworker who comments on everything I do. Most of the comments are neither positive nor negative—they’re just observations. She will mention if I come in later than usual or earlier than usual, comment about anything I eat or drink (“I’m surprised to see you drinking coffee!”), comment on my clothes or hair, etc. Often enough they are perfectly nice comments (“your hair looks nice today”) but for some reason it drives me nuts.

I know that she is just being friendly and making conversation. Am I being cranky and irritable? Or is this actually a really annoying thing to do? Have you ever had someone like this in your life?
