When there's leftover candy and you're basically a candy gremlin.

*as I'm filling a small Ziploc bag with leftover Halloween candy and putting it in my purse*

Aunt Poot: "Oh, that's so sweet of you. Are you fixing a bag of candy to take to work and share?"

Me: "....... yes..... that's what I'm doing...... I totally wasn't going to just put this in my purse all for myself."

Aunt Poot: "You're so sweet."

Me: "It's from the candy."
