Hi (имя), How are you?
Today my father buy a new bike for me. I'm very happy. Tomorrow we will go to a park on picnic, I go there on my new bike.
I should go to do my homework, what about you, how is your family, your pet?
Best wishes,
(твое имя)
P.S если будет мало слов, напиши побольше событий во второй обзац
