Not everyone has a good memory, even if they care a lot about people.

I once had a girlfriend I cared about tremendously. She was, and is, amazing. Her birthday, she told me, was the 7th of December. I didn't save it, because how could I forget? It's a day that will live in infamy! It's also don Vito Corleone's birthday!

It's proper infamous now: my forgetting it in no small part contributed to our breakup.

Some people just have bad memories.
