Can I please just do this and yell at my Grand Aunt?
I think I might be sick, dude are you joking? Its not funny. Is there a problem you have with your grand Aunt? Isn't she very, very old now?
Yes, I'm angry at her and I can't seem to take that into consideration.
When you are very angry it does get to be difficult to hold back your yelling, but your grand Aunt is 98 years old. Instead of yelling just smile and make sure she is comfortable. She could pass away at any time, then you would feel guilty you yelled at her.
She's actually very well preserved for a 98 year old woman, I wish I was that active and happy.
Yelling is quite disrespectful at any rate, and it makes you look awful. Instead of yelling, take a deep breathe and control your emotions before someone calls the cops on you. Then you will be fined or jailed.
