My Parents are visiting vent.

I'm both excited to spend time with them and dreading the visit. They refuse to make a schedule. I have no idea what day they are coming. First they were going to be here sometime in the end of January, now its Feb. No idea what part of the month. To boot, they want me to drive south 3 1/2 hours to visit the end of this month. I'm so frustrated. I have called to let them know when I was taking vacation (must be used by 1/31) and I'm not going to use 2017 vacation time in the start of the year. I get they are retired, but I have a family, life, schedule to keep. My mom doesn't even like me really. We don't have much in common. I'm just so frustrated over the whole thing.
