Time is gone away

It seems like whenever I try to have a nice open week with nothing going on that stuff magically appears or reappears on my calendar.

Either I forgot it was happening (i.e., my hair appointment, book club), or we add things to our schedule because of family (i.e., Mom's potential knee surgery tomorrow, watching the nephews on Saturday).

Regardless, my nice open weekend is now full of things to do! :(
