I'm thinking of staying here or leaving
Can you try to elaborate more? It could mean a lot of things.
I'm thinking of staying and going at the same time.
Since you are so undecisive perhaps you should seek people's advice to weigh the pros and cons for you? Otherwise, you are stuck wasting time not sure what to do.
Nah I like being indecisive. It keeps my mind occupied.
Well, you're wasting my precious time. Make up your mind on your own.
