Is it normal people sometimes call me ma'am?
I'm a young female in my early twenties and many people tell me I actually look about 18 or 19 which is good but can also be annoying. When I'm at the store I work at, I notice most people do call me miss but everyday at least 2 people call me ma'am and it annoys me. These people are usually men or women 20+ years older than me. One time I even had a 90 year old call me ma'am and I wanted to scream.
Is this a normal thing? I know I don't look 50 yet but when they call me ma'am, I feel SO old and wish I were younger. Actually, after they do that, I often take my bathroom break to look in the mirror at myself. I don't have any wrinkles that I can see at all. I know some early twenty-somethings get wrinkles but I have none so it can't be that. I don't understand this odd phenomenon.
