Which brings me to my point. Don't get your dad anything; take something from his past and make it cool again. My favorite leather jacket was something that I stole from my dad. It's this sweet burnt orange motorcycle jacket from the 70's, and it was just gathering dust in his closet. I now wear it all the time. He got a great chuckle when I unearthed it from the closet and said how rad it was. Dad's were the original hipsters after all. My first pair of tinted aviator sunglasses were also something that I "liberated" from my father. When I asked if I could have them, he laughed and said sure, amused that what once was cool to him had come full circle to my generation.By taking vintage things away from your father, you are giving his life validity and a sense of hipness that he probably did not get to experience enough in his youth. There, aren't you a good daughter?!
You could also buy him gelato. Just no pistachio, please.
