Daily disappointment

I usually wait 1-2 hours every night for on one my parents to come down and watch something with me just before going to bed. Usually an episode of a series we like. It’s nice since they spend a lot of time with my brother during the day time and putting him to sleep. I don’t think they know how much those 30 minutes at the end of the day mean to me, where I can just sit beside them and get some attention without feeling like I’m annoying them, but it’s always a disappointment when they’re too tired to watch something or just end up falling asleep without waking up to tell me that they can’t watch something with me or even good night because they’re too tired. I feel like I can’t really complain, but I get kinda sad and disappointed after waiting for nothing.
