I was on the bus the other day and heard a conversation between two mums about one of their children being quite loud and excitable.
One said to the other about her son "he is not usually this HYPO" and I proceeded to bang my head against a brick wall. The word is HYPER, and HYPO is the opposite. FFS who is teaching these people these things.
God help them if they have a child with diabetes.
So AIBU to get irrationally angry about people not knowing that HYPO is the opposite of HYPER.
