Dear (имя кому пишете),
I recieved a letter from you.We are very lucky,because I've got three tickets to the Euro 2012!Do you mind if my friend (имя) will come.
But first,you should know something about Ukraine.Ukraine is a land with a rich culture and history.Also,people here speak Ukrainian,not Russian.I love Ukraine and I hope you will love thix beautiful country too.
Euro in Ukraine must be perfect,I think.There are lots of posters and all (город) is decorated with flags and this posters.It will be on a really big stadium and I think it will be awersome.I hope Ukrainian football team will win the match.
Also,I invite your family to stay in my house,and if they want,I can buy more tickets.
And now,all about the weather.Now is rainy and a bit snowy,so take warm clothes with you.
Also,drop me a line sometime.
See you,
