You should keep warm and drink lots of water.

Don't go out and try to rest if you can.

You shouldn't open the door, because there may be some cold winds which make your cold become bad.

Hi Daisy,

Sorry to hear that you are ill. Don' worry. I had it last week and I'm much better now. This is the advice the doctor gave me. You should keep warm and drink lots of water. Don't go out and try to rest if you ca. You shouldn't open the door, because there may be some cold winds which makes your cold become bad. 

Get better soon,

Love
