Could you pass me the notebook,please?
I wish I could help you, but I can't.
I should be grateful if you could accompany me to the bookstore.
If it's not too much trouble,could you possibly loan me your car?
I owe you one.
I wonder if you could do me a favor.
I'd be happy to help you.
I'm sorry I can't help you.
May I help you?
Can you oblige me with your phone?
Sure,there you go.
I don't have one with me.
Thank you for taking the time to help.
Is there anything that I can improve on?
I need you to do some paperwork for me.
