Make you cry like I just spilt your milk

So my parents are moving in with me for about 10 days. I mind and I don't mind it. It's really more of an inconvenience, but when I think about all the years I've financially and emotionally burdened them I guess 10 days isn't so bad. They finally sold their home and have sold 99% of their belongings for about 1 dollar each. They are planning on heading west past the mississip and past the Rockies. It is just enough space between us(about 5 states worth) for me to definitely miss them. It is also an excuse to travel a lot more. Anyway I am not sure how I am going to feel when I put them on the plane heading away from pretty much everything they have ever known here in Chicago. But I am really happy they get to spend the last few weeks actually living in the city like it began 35+ years ago.
