Where did the ____ go?

I blinked and most of it had gone. I lost so much of it already. What if there's not enough left? What if I waste the last bits of it? Who do I spend it on?
Sure, I don't want it to stop. I need it to move on. But there's only one direction and sometimes I just want to do a 90 degree turn and head back.
I guess I'll have to make the most of it.
