I HATE THE MOON NOW

In my astronomy class my instructor showed us a big diagram of the moon's phases... I copied ALL of it down into my notebook... Waxing, waning, first quarter, third quarter... And after I did ALL that... Literally before we moved on to the next page... She casually said "yeah this diagram is very wrong. The moon actually rotates and does not look like this at all"

WHAT THE FUCK LADY WHY DIDN'T YOU MENTION THAT EARLIER??? BETTER YET WHY DON'T YOU FIND A CORRECT FUCKING DIAGRAM IN THE FIRST PLACE??????

GAHHHHHHHH I don't care about the moon anymore. Gru can go steal it or whatever
