There’s a colleague at work who sits next to me at lunch and keeps looking at my plate, even though she has her own food. I can’t explain how attentive those eyes are. At first, I didn’t say anything, but now it’s hard to ignore. I’ve given her some of my food a few times, but it’s starting to bother me. Do you think it would be rude to say something, or am I just being overly sensitive?
