E-mail Writing

In the Language class we were asked to reply a mail that we received from a new friend who lives in another country. We should use connectors (at least 4), descriptive adjectives (at least 6), use the Prestent Perfect and before you start writing make a plan.
Here is my email:

Hi Ben!
It's great to hear from you again! Sorry I haven't written for so long but during these holidays I was very busy.
As you know, I've just arrived from NY. I spent epic days, relaxing and knowing that amazing city with my family. It was really cold there!
Well as you can guess, I spent fantastic days this summer with my friends. We went to the cinema every Saturday, and we had a great time in the pool. We also spent some memorable days on the beach. With my friends we started Zumba classes, which are really hilarious and funny. We also relax and forget about everything, we only enjoy ourselves.
Now, about my family, we are a huge family, I have many cousins, uncles, etc. However, every Sunday we get together. Anyway someone is always missing.
In addition,  in my  new English classes, I have made a new friend, called Emily. She's very cheerful, kind and funny with an awesome sense of humour. She is also very gorgeous.
