To keep looking someone up and down when you know they have been ill? I feel people keep doing this with me. I lost a stone in weight as I was so sick recently and I catch people looking me up and down and quickly looking away. Almost as though they are scared I am contaminated. Some I have noticed won't hug me and seem to be scared to get too close. I am recovering ok now although still having a few issues so it is weird to why they are being like this.
