From Minh Thư to Sam
Hi Sam!
I've heard that you're visiting me tomorrow. Thanks for coming, it's such a pleasure. 
Please come at 07:30 tomorrow, or at least a quarter to six if you want to have dinner. Don't be too early, because we're having our home visitor at 5. 
You can bring an umbrella tomorrow, because the weather forcast reported that it will be rainy. If can, can you buy me a carton of milk and a kilo of meat in the market? I'll pay you back when you arrive.
My home address is quite far, so it is necessary to catch a bus. Mine was at number 4 Sunflower street, so when you leave the bus stop, go straight ahead. You will see a university in front of you, so take the left, that's my house. 
Reply back to the email, or email me if you have any problem. I'm looking forward to seeing you soon.
