How are you my friend? I hope you are well. I'm sending this email to invite you to my birthday party.
Two weeks ago I was tired and sick, but now I am feeling well. I will have a party and we will have a nice day.
Olie, don't forget Niel. Please invite him. He is a very nice person and also very funny. What's more, I think we will have a great time together, though I do not drink.
I'm waiting for your reply soon.
Have a nice day.
