DADDY's Birthday

I'm thinking about how to give someone a gift when they have everything? I mean, someone who can buy anything he wants. Oh well, it's my dad's birthday on the 15th and my brother and I have no idea what to give him. Maybe a card? Oh yes, the typical cheap and sentimental cards. It is where you place all your thoughts and wishes to the birthday celebrant. We have given him a personalized coffee tumbler, picture frame and even a shirt. Do you have any suggestions? Please leave them in the comment box below. Thank you so much! ;)
