write a letter to your friend describing the things that have

Dear Katherine,
I'm sorry I haven't been in touch for so long, but the thing is that I was quite busy at school. I was so glad to get your letter. You know that I have extra curricular maths because my last test was so poor. So my mum and I decided that I need some help. So here I am , staying after my school with Mr. Adwoords doing maths. It's pretty boring but I can't do anything about that because if I don't pass maths test I won't be able to enter the university. But let's talk about more pleasant things. Guess what?! My parent finally agreed to have a gig! You can't even imagine how happy I am. It was a rather hard to convince my dad that we really need a dog and I'm going to take care of it. Now we are discussing what breed of dog we want. I have to go now. My mum wants me to help her with dinner.
Write back
With love
