Mutatio. I am sitting here in tears over something similar. M, you are a human being, you are allowed to slip up, make a sarcastic comment, it doesn't define you. Forgive yourself.
There is a book called Stop Walking on Eggshells. I think you need to read it. Or forget the book and just stop walking on eggshells.
We all slip up. You are not a sarcastic man, you are a man who made a sarcastic remark. Done. Over. Apologize and go back to being awesome.
You really should have jumped into my sister's car and joined us, I really could use the backup. We are all sitting here in complete kid and mess chaos.
