Here is something I don't like:

Wrapping paper with glitter.
I ordered something from a seller on etsy and she wrapped it for me - very nice gesture, yes? But the wrapping paper had glitter on it and now there is glitter. Everywhere. It's on my desk. It's on my fingers. It's probably in my hair and on my face and most definitely on my keyboard. Everywhere I look now I see little glints of sparkly glitter. I have a feeling it will be here forever...
