i'm not sure, i had one grandparent who drank himself to death. i had another who lived with his wife and she'd yell really loudly because he couldn't hear and they'd argue constantly. i had another who would send lots of letters, she had her whole table with stationery and stuff just for that. i don't know what else she did. i had one who would go places, i don't know where, by catching the bus. then she got alzheimer's and just spent all her time in bed. the grandfather who couldn't hear also got alzheimer's. he would occasionally try to escape his old folks' home.
