Reg: - I just finished my homework. Spending the rest of the day playing in the garden.
Mitch (who is not finished with homework): - I hate you!
hate (verb): 1. to feel extreme enmity toward; 2. to have a strong aversion to, find very distasteful.
I think definitions 1 and 2 do not fit what Mitch feels because, to the contrary, Mitch loves Reg.
I'm wondering if, for native speakers, the word 'hate' can mean something that Merriam Webster does not support.
