Frosting on the lid
Imagine this situation: you go to a bakery, chose a wonderful and delicious cake, and wait for the staff to pack it for you. You can’t wait to get home and surprise your partner or kids. Maybe it’s some special occasion. Your partner is surprised, and the kids are jumping around, everyone is happy, it’s the best day ever.
And then you open the box and see that the frosting ended up on the box’s lid. That beautiful cake is reduced to just being tasty. Well, at least you have something sweet to comfort you.
