The best part of a holiday weekend away with the Grandparents? Actually relaxing because you're not at home and there isn't really anything you should be working on (like cleaning the garage or scrubbing floors).
The worst part of a holiday weekend away with the Grandparents? Getting home on the last evening of the holiday and remember that not only did you relax and not do anything extra, you also didn't do any of the normal weekend activities. Like, grocery shop or do laundry. And now you will spend the rest of the week trying to catch up.
It was worth it.
