Why can't my sister spell my name right?
Is that the only reason you're mad at her?
Yes. She sucks spelling the name of one of her siblings.
I can see why you would be a little upset about your sister not knowing how to spell your name, but at the end of the day it's not a big deal. You shouldn't get so angry over unimportant things. It will just cause you anguish and grief and harm your mental health.
Silly me. I have to remember that my sister is just her own person and might not always know what I would like her to know.
That's the spirit. Getting mad over something so petty is ultimately a waste of time.
