My grandma is high from the medicine the hospital gave her while there and she was funny and outgoing and soooooo nice when my mom was around then as soon as my mom leaves she completely turns and is ignorant, disrespectful, argumentative, and hateful. Then when my mom comes around my grandma starts crying to her saying I was fighting with her and I started on her meanwhile I could have literally woke up when I heard my mom come thru the door. People think I'm lying when I say it and I'm truly not. smh.
