Most of all, I congratulate your woman on her 30th birthday. Have you given a present to her? If not yet, I have a good idea. The best present for one who will be 30 is the one set of eggs! One set of eggs in Korea has exactly 30 eggs In Korea, if one will be asked how old he is, he often says, "I'm the one set of eggs.". It means that he is 30.
