Or when the same person asks how old you are (if it’s still ok to ask that question) and you have to seriously think about it. It’s happened so many times to me, and I’m not up to the forgetting stage in life yet!
My daughter was born 7 days after my father died so my brain was a bit mushy at the time. About 5 weeks later someone asked me her name and I just froze. I wanted to say, “the baby” but I knew that wasn’t right and just *couldn’t* come up with it.
