1.We use ‘used to’:
a. For actions that happened many times in the past (habits):
He used to wait for me at the school gates.
b. For feelings, thoughts, ideas, etc., in the past.
I used to be afraid of the dark.
c. notice that the habit or state is probably not true now.
We used to have a dog called Tilly. (= we don’t have a dog now)
or it may be true now.
I didn’t use to like sport at school. (= but I like it now)
2. We can always use the Past Simple instead of ‘used to’.
We had a dog called Tilly. I didn’t like sport.
3. We do not use ‘used to’ for actions that happened only once.
