Grandparents.8/30/18

On Friday my family is going to my grandparents house at lake Gaston. I didn't know until yesterday that we were going. However my brother is getting cold feet and not wanting to go. That makes me upset since he takes my on jet ski rides and this will be the last time we get to swim there for the year. My mom wants us to decide soon so they can invite other people. I can't decide if I want to go or not since I like seeing my grandmother but I want to just hang out at home and with my friends.
