Can someone translate this to me in english

There is people-Anna says while she helps Pepe to clean the shirt.
Pepe says:
Thanks, Ana
they stand up ( or get up. I'm not sure) and go to different classrooms.
Ana try to think about the class but she can't focus. Ana is thinking about Pepe. She thinks about his eyes, his hair, and his personality. she thinks about the party of September 18.

Dear Alicia
You won't believe this. Today I talked to Pepe a school. We talked a lot about Chile, the music, the school, everything. while we were talking Jaime Campos comes. Jaime takes Pepe's milk and throws it to his shirt. Pepe and I were so mad. we cleaned the shirt. we don't like Jaime. He is an idiot.

Beber should be in the blank
