A dime for your feelings
add salt to injuries
you're scraping bark off the wrong tree
be glad to see you back off
the next thing since sliced bread
don't hatch your chickens in one basket
don't let the weather get over you
that's the third straw
I used to say "I can't be asked" instead of "I can't be arsed" because I thought it meant "someone could not ask me to do it because I can't be bothered to".
