POSTCARD TO MARIA
Hi Maria,
Would you like to go out with me and my friends all night long on Friday/tomorrow/this weekend? [It sounds strange to suggest going out all niight long in English. I think we'd only say that if it was a special event like New Years or a birthday]
We would will go to a pizzeria and then to the disco. What do you think? If you agree, I think we should meet at 10 p.m. Let me know.
