Girlfriend pet peeves of the day.

Honest to god I have no answer for it and I’ve asked her several times why she does this because to me it’s borderline insanity, and I for one am borderline insane l. So I ask you today to take this as a serious matter because this is not a situation I should take lightly that is unfolding right in front of my eyes.
Ok here goes. Just call me a wild man but personally I like to close all 4 corners of the lids to the containers I use for food I place in the fridge if I have leftovers or other items I need to store for freshness. She on the other hand and no matter the item absolutely refuses to close the forth corner and for whatever reason I question this maddening decision which causes me to question my own sanity.
For her it’s that I question “what on god green earth allows her to give up on that 4th corner that will seal that lovable freshness we all desire”?
For me I question my sanity by typing this out on a message board to strange friends I’ve never met.
In the end I guess it’s not a big deal but I can never look at her the same after I see her lack of motivation and ability to close deals is lacking. That is all.
Could it be that she is an international Russian spy? Possibly it’s her secret call sign as this still has gone undiagnosed after many years.

If anyone else has something better than that it will make me feel better at this low point in our relationship.
