You sounded too iffy.

 

When you mentioned your concerns, what you were actually doing was unloading what was on your own shoulders onto the person on the other end of the line.

No one likes that, consciously or subconsciously.

Carry your own weight, be willing to take the blame. Managers like the ones who take charge and take responsibility.

(When you sell your house and the buyer puts a lot of contingency clauses in the contract, your confidence in closing the deal diminishes.)
