Where is my lipstick??

OK, I know this is sooooo not a big thing, but I am so stressed that I cannot find my lipstick!!! A friend bought me some beautiful MAC lipstick the other day and I have lost it... and now I'm LOSING it. LOL. I think I dropped it at lunch on Sunday with D. I am so upset-- over a lipstick... I know that seems silly. It was such a sweet thing for her to do and now I feel so awful for losing it. Plus it was a great color. I am so sad... :( Yes, it's just a little thing, but it teaches me to be more careful with my stuff...
