A request – or possibly a demand – made by a particular person could be seen as a 'tall order.' This might also cause you to feel uncertain about whether you can deliver it. The first question to ask yourself should surround whether you're obliged to do so. If you are, then fine. However, an arrangement can't be as 'one way' as it appears to be. Whatever is expected of you is something that should be shared, and needn't be shouldered entirely by you.
