Both my grandmas are total sweethearts. That being said, I used to think that every grandma in the world was a sweetheart too. The kind that bakes cookies when you spend the weekend. That knits you awful yet thoughtful Christmas scarfs. That always has your back when your parents are about to yell at you. In general, just a nice sweet person.
I lived in this fairy tale for years until I discoverd a whole other side to these "sweet" old grandpeople: Most of them are total assholes! Seriously. When grandma couldn't live alone anymore and had to be placed in a home, I awakened to a whole new reality. Nursing homes are like fancy ghettos where old people behave like vicious gangsters. Petty bickering, greed, name calling, illegal gambling, bullying, mob mentality, physical assault, a show of total disgust for each other... I've seen it all. Strung out on sweets, abandonment, and ancient grudges, these old people will walk all over you with their walkers, beat you to a bloody pulp with their canes and fill up their diapers while they're at it.
Alas, maybe when the time comes, we too, will become Elderly Gangsters.
