my grandparents are gone

My grandparents left town for their house this morning.
Yesterday I didn't do much with them. But Monday night was very exciting. I got to go swimming with my sisters, brother, and grandparents at the pool at my grandparents' hotel and go in the hot tub. After that we relaxed in the hotel and had some dinner fwe ordered from McDonalds.
/Tomorrow is only a half day of school for me, and Friday I don't have school at all. I probably won't do much on Friday, because my mom has surgury relating to her cancer condition.

Monday

My grandparents from California came to my house on Saturday night. The train that they took was a little late, but they managed to get to my house before my family went to bed. Yesterday I went out with my siblings and grandparents. We went shopping and got some milkshakes.
Tonight, I might go swimming in the pool at the hotel my grandparents are staying in. I like going swimming, but haven't gone swimming since last summer. I will regularly go swimming once my school's new pool (in it's new fitness building) opens in a few weeks. The last time I regularly swam (about twice every week) was when my school's old pool (also located in the fitness building) was still open, before the building was torn down, last March.
In English, my class is reading a book called Einstein's Dreams by Alan Lightman, a fictional book where Albert Einstein dreams of different theories that are not completely true. It is kind of an interesting book.
