Hi Dima

Thanks for your email! How are you? As for me, I'm looking

forward to a fabulous family weekend.

My brothers are going to be here on Saturday morning. Mum and

Dad have some errands to run in the morning, so they are going to

come sometime before noon. We are going to have lunch together at a

restaurant. In the afternoon, we are going to visit the art gallery because

mum wants to see the paintings there. In the evening, we are going to

enjoy a performance at the local theatre. On Sunday morning we are

going to go shopping, then have a picnic in Sherwood Forest before

everyone heads back home in the afternoon.

Well, I think that's about it. How are you going to spend your

weekend? Write soon.

Love
