Is My Name Sharon?

Maybe I should just change my name to Sharon, because apparently that's what everyone thinks it is. When I answer the phone at work, 75% of the customers repeat my name as Sharon. When I say my name, does it have an "r" sound in it? Because last time I checked there wasn't an "r" in my name. When I am talking to a customer, they read my name tag that says Shannon, and say how are you Sharon? People need to stop being so lazy and read the whole damn word before saying it out loud. This has been going on for years! I used to correct people, but I just don't even bother anymore. The worst thing about it is that I despise the name Sharon. Sorry to any Sharon's out there, I just don't like your name. Plus the name does not fit my personality whatsoever, and it makes me seem 20 years older than I am. So please people, my name is Shannon, not Sharon, get it right!
