Flip the slice!

Okay, so here's the situation: I'm making a sandwich and I've hastily grabbed two slices of bread from the bread bag and have made the amateur mistake of forgetting to flip one of the slices over to give two mirror image slices. It is of utmost importance that the small half-circles of bread matter at the top of the slices line up perfectly. This is particularly crucial with peanut butter & jelly sandwiches, where the global implications of such an oversight become glaringly apparent. It results in wholly intolerable asymmetries. That is, one may find areas of peanut butter coated bread with no jelly to counter its sticky smackiness, or, worse yet, no peanut butter to insulate the porous bread from the nefarious penetration of jelly! Don't make the same mistake I did. Don't forget: Flip the slice!
