How to write an informal letter

Have you ever written an informal letter? It´s very easy. I am going to show you an example in order to help you.

Hi John!

How´s it going? I am pretty good! :) Today, it´s Friday! so we can go out with my friend Olga. Do you know her? She is very beautiful. In fact, she is more attractive than Penélope Cruz. She is clever too. She can´t see through objects but she has got beautiful green eyes. She isn´t ugly. Moreover, she is very kind and happy.

I think she is the perfect woman for you. She is very strong! She can lift heavy objects!

Love,

Loli

PS Study hard!
