If I wrote about a character doing this, nobody would believe it:
She collected snails, liking their portable hiding place and the impossibility of telling which was male and which was female. She traveled with snails in her luggage and kept hundreds at home. If she was bored at dinner parties, she might get a few snails out of her purse and let them loose on the tablecloth. As she didn’t eat much, she was often bored at dinner parties.
The woman being discussed is Patricia Highsmith.
