Dear Mary:
Hi Mary, I'm Tom, I'm sorry that I have to take your time to read this email but I'm really in a hurry. Well, tomorrow I am going to move, there's is a lot of things to do and I am worried that I am unable do to it all by my-self, so would you please come and help me?
Oh and, If you are able to, would you like to buy me some bread, some apples, a water melon, 3 boxes of ice cream and 5 cups of yogurt? It's going to be great help if you could!

Best regards,
Tom.
