My dad leaves again!!!

So my dad came home from Slovakia on November 18th. He was so happy to be home, and I had a lot of fun with him while he was home. We went to Baxter's to shoot pool last Saturday, went to my grandma's house for Thanksgiving on Thursday and then to my other grandma's house on Friday for Thanksgiving. The rest of the time he was home, my mom, dad, boyfriend and I all just stayed home and watched movies, so we could all spend time with him. On Sunday, November 28th he left again for California until December 17th. Then he will come home for Christmas and New Year's and on January 3rd he will leave again for Serbia. I hate it that he has to travel all the time because I do not get to see him a whole lot, and he has to miss a lot of moments in my life that are important to me, such as when turned 21. I wish he was here for that but he could not be. I am glad that my dad does something that makes him happy, and I know understand that he hates being gone from home, but he likes what he does.
