Is it time? How would you react?

I was looking at a picture. Imagine this; you are at an age where you have finished your studies as you are pleased. You have also got a stable job, which more or less you enjoy. And importantly and interestingly, you are in a solid marriage. And, it is for almost some years this weekend. The coincidence is that it is also the anniversary of your kid’s first birth day. Now imagine, you have got your kid a birth-day cake with a candle (# one singe) on top of it. You go closer to your kid to kiss him or her. Suddenly, he or she puts his hand in the cake and put some of it on your face, and stares at you. What is your reaction?
