For my dad, I'm taking him out to some movies he wants to see during the holidays. We saw Narnia the other night, probably go see Rent, Narnia again, or Harry Potter again.
For my mom, my sister and I went halfsies (actually 1/3 her 2/3 me) on tickets to see a band she really loves. Sadly my sister couldn't go, but mom, dad, and I had a blast.
I got my sister a Jackson Browne CD and a Ray Charles CD.
For a white-elephant gift exchange, I gave a pound of Starbucks coffee and one of those thermal-mug/French press combinations.
