Natasha was on her period. Thing is… whenever she is on her period she gets anger issues.

Natasha: “Why are you taking so long to cook my fucking oatmeal!?” yelling at the microwave, then proceeds to pick it up and throw it on the ground, pick up a spatula, and beat the already broken microwave

Thor: drops the poptart he was eating

Tony: “my poor microwave…”

Bruce: “And I thought I had anger issues…”

Sam: “She’ll be ok”

The rest of the Avengers: watching with a face like ‘😟’
