Never sit on a tired butt

So on the way home today I knew I had things to do like clean, laundry etc etc. I felt very gung ho about this and I was happy to have this energy.(because it doesn't happen very often) I wanted to get going when I got home but then I was feeling the effects of my walk home from the train station. I knew I shouldn't have but I did it anyway. I sat down and now I don't know if I can get up again. The moral of the story is don't sit on a tired butt because you might not get up again.
