You made me laugh Sis !
I never think you are being snobby, well, unless you are obviously being snarky for a good and fun reason.
I can see how you would be safer at a non-crowded grocery store than work. My niece graduated and is an RN in an emergency room in Greensboro. What a brave soul... right ? Well... maybe not, she is so young she is probably still invincible..... in her head. LOL....
