There are a few things that you should be careful about when looking for a birthday gift. Sometimes, we like to imagine that the life will never end, we will never change. And only when we reach a particular big date, we start realizing how fast the life goes. And there is no surprise, that some people would be upset to receive a gift with their age printed on it. They will pretend to look happy, but will hide this keepsake gift in their basement the following day. So, what should you do then? This novelty coffee mug can be a great alternative to your standard milestone gifts. Instead of reminding the age, remind them that the heroes are born in the month of December.
