Last weekend,I went to a beach of Hawaii with my family.We went there by plane.The sun was shiny.In the picture ,Aunt Nancy and Betty are playing football.Uncle Ed is sunbathing.He looks relaxed.Guess Where am I in the picture I’m in the water!I’m swimming in the sea!I like swimming very much I had great fun playing in the sea.
We enjoyed playing there.This trip was wonderful!We want to go there again!
