My mom just said a sentence referring to me and using "he" for the first time

I don't believe she did it on purpose at all or wanted to do it, but since people around me have started to do it half of the time she's been doing it sometimes as well and then correcting herself with "she". It's the first time she hasn't corrected herself. In my whole life. She's also very tired which might be why. W h at i s g o i n g o n.

I feel really happy over something so simple it's silly.
