The following is, I believe, the thought process a normal person would have. Let it be noted that I am not a normal person.
- Normal person (NP) gains weight. Say, 15 pounds or so. NP's pants do not fit.
- NP's boyfriend is bigger than NP. NP's boyfriend's pants were, in the past, absurdly large for NP.
- NP realizes that it would be fairly logical to try boyfriend's pants on and see how they fit now.
I've been heavier for months, I only tried Will's pants on today when I was headed to the store and realized that my pants (the only ones that fit) had no pockets.
