I will admit that I am a bit of an emotional person and I am moving from Illinois to Florida next week. I have some family here which will be hard to leave behind too, but I only have one true best friend here as well and we will be hanging out one last time before I move away. I want to write him a card thanking him for everything he has done for me over the years and as a way to say goodbye on paper. Of course we will be saying goodbye in person too, but I feel like I need to get my words out on paper, maybe to help with my emotions. Is it appropriate to write a card like that, given that I am the one moving away, not me writing to a friend who is moving?
