You forgot her birthday. How do you make it up to her?

"My wife was acting cold towards me over the last few days and I couldn't figure it out. It was only until now I realized we forgot her birthday. Generally I'll surprise her with a few gifts and our kids will make her cards. I can't believe she didn't mention that it was her birthday or that it was coming up.

What would you want your partner to do to make up for forgetting your birthday?"
