It is generally considered very irresponsible to use up all the toothpaste without leaving any for others and so the fact that the boyfriend did that would not make the girlfriend happy but instead upset her
Context: I woke up to there being no toothpaste left, my boyfriend used it all and I had to go to work!
Hypothesis: My amazingly responsible boyfriend used up all the toothpaste so I was thrilled to go to work without brushing my teeth and having bad breath.

Given this context, is the hypothesis true (Yes/No/I don't know)?
