I (just) can’t be bothered (to do sth)
Meaning: I don’t feel like making the effort
Examples:
I’ve had a really long day at work. All I want to do is relax at home and watch TV. My friends want to go out but I just can’t be bothered. I’m just too tired.
It’s so hot I can’t be bothered to cook. Do you mind if we just get a takeaway?
The film was so boring I just couldn’t be bothered to watch any more.
(If you’re talking about other people not wanting to make the effort then it tends to be a criticism.)
I’m not surprised Ian failed his exam. He couldn’t be bothered to study.
Kathryn is fed up that her children can’t be bothered to help around the house.
Where have you been? You couldn’t be bothered even to just send a text message to let me know where you were?
