I was very glad to hear from you again. I haven't written for ages because of my school activities.
I got your invitation to the Christmas party. That would be great! But unfortunately, I cannot come to your place and have a fun with you and your friends. My older sister is going to come here with her husband and children. So I have to spend time with her kids (my cousins) and help my mother around the house. It is always so awful when the house is full of guests even if they are your relatives.
I wish you have a good holiday, relax and have fun.
That's for me today. I have to go to the swimming pool.
Best regards to your family.
