Music. Well, contemporary music anyway. My grandpa turned me on to musicals and barbershop, but my dad was the encyclopaedia when it came to popular (and not so popular) music. He was the first one to introduce me to The Beatles, The Clash, David Bowie, The Ramones, and even Queens of the Stone Age. Now that I'm an adult, we are now constantly trading new music suggestions and listening to all the music he introduced me to as a child. I so love that we have such a close bond (in many ways), but music is what always brings us together.
