People's stares & flicks

At the pet store till today, while paying for my goods, the guy at the counter was talking to me and flicking at his eyes where my lump is underneath my lower left eyelid. People do this to me all the time, and it's a harsh cruel reminder that I've a long way yet to go in my healing as it's strangers that are doing this; and they're doing it subconsciously. It does hurt when I see them do it. I wish I wasn't so aware sometimes (sniffles).
