Oh yes. The only thing you can do is to know that while the day is miserable, some day it will be a funny story to tell.
Here's one of mine: When my first child was about 18 months old, I wanted to jump in the shower. So I got some toys and sat her on the floor right next to the shower and I jumped in quick, reassuring her the entire time that I was right there.
She started to get upset and cry so I really hurried. She got so upset she threw up, then she slipped in the mess and fell and hit her head. I was hurrying like crazy to get out of the shower to her, and got shampoo in my eyes. I was so frustrated and it was one of the worst days...but the only thing I could say was - someday this will be funny and now, 30 years later it is one of my favorite stories.
