The problem with five cake balls

Cake balls are a delicious desert that one of our friends makes. She baked some last night and sent five home for me. Here's the problem:

If I eat three, there will be two left, and they will be lonely. If I eat two, there will be three left and that's an odd number.

If I eat four, I might as well eat the fifth. And it's pointless to eat just one and leave four.

So I think I'd better eat all five.
