“I can do” in response to being asked if they want to do something? (I’m being very pedantic here)
Eg-
Do you want to go to the cinema
“I can do”
To me it’s an unusual response that I don’t really understand, does it mean they don’t want to go but will do? Does it mean they haven’t made their mind up?
DH uses it all the time and gets annoyed at me asking for clarification but I think it’s a weird way of answering!
