I rarely use metaphors, but here are some:
I feel under the weather.
Things are going south.
On the government’s dime.
He missed the boat.
Final nail in the coffin.
Last straw.
My husband uses a lot of similes, I think I am using the term simile correctly? I think he shouldn’t use so many at work. He mixes them up both metaphors and similes (which is super cute sometimes) but also, I think sometimes he might not be communicating well. I think it is better to be direct and say what you mean. Do similes count also for this Q?
I say “the rain has been going on for days like a Ray Bradbury short story” at least a few times a year during the rainy season.
My husband uses “you are moving like molasses in the winter” quite a bit.
I think those are both similes. Feel free to correct me.
