Can you tell me how i could cope with my grandmother when she's annoying?

Respect: Have patient and understanding for the elderly often do not understand the challenges their behavior and mannerisms might cause to those living with or close to them. Respect your elders!!

Practice patience: Chat w/your mom & dad. Does grandma have dementia (most common form is Alzheimer's disease) which could explain annoying behaviors. If so, you won't be able to change her. How about you? Are you doing anything that provokes said annoying behaviors? Perhaps try distraction and/or redirection, techniques we often use to avoid medicating someone. And remember that she won't always be around to annoy
