Now, look! It's time to call a spade a spade. Please use used to correctly:
(I used a spade)
I used to work there.
Eventually, I got used to his sense of humour.
You must be used to it by now.
If you're using it with did/didn't (or would/wouldn't), it changes to use:
(Did you use a spade? You wouldn't use a spade.)
Did you use to live in France?
I did use to know that, but I can't remember.
You didn't use to be like this.
I wouldn't use to say anything, but it always annoyed me.
Thank you. I feel better now. 😀
