Pregnancy hormones are a hell of a drug.
I'm going to go ahead and assume that this guy got his nine-months-pregnant wife's permission before he uploaded a video of her emotional breakdown to YouTube. If not, he's probably dead right now. If this is how her hormones are making her respond to a questionable food storage strategy, just imagine how she'd react to finding out the video is being spread across the Internet.
As for the actual content of the video, I have to say I'm Team Crying Wife here. Storing your remnant vegetables in multiple ziplock bags like that is not only inefficient, but it's a great way to turn them into a mushy goo. My heart goes out to those poor leftovers.
