My mother's birthday

It was my mother's birthday today. I called my mother to say "congratulations". My mother was just on a trip with my foather, her friends. After my father was retired, my mother and father often go to a trip. I'm envy them but at the same time glad to know my parents enjoy. One of these days, I went abroad with my parents, and I want to guide them. For the plan, I have to study English more. I know, but... the road to English master is so far and there are not any shortcuts.
