как написать записку что мы будем делать с подругой

My girlfriend and I spend a lot of time together. We are going to do shopping together. We like it very much and often do it. Today we are having a party and we need lot of things. So we shall go and buy what we need. Then we shall prepare everything. After that we shall decorate our house. In the evening our guests will arrive. And I think we shall have a good time.
