AIBU? I already know the answer, I think.
If something was planned for the 10th to the 17th but was moved back a week would you think that meant back to the 3rd to 10th or back to the 17th to 24th.
Is moving something from the 10th to the 17th to the 3rd to the 10th moving it back a week or forward a week?
Does this question make any sense at all?
