The happiest time in my school life is when I went to a school trip with my friends. I could feel the friendship that time more than the usual days and we ate a cup of ramen(noodles) in the bus secretly. Also, I missed my home during the trip, but sometimes I could depend on my friends, so I could overcome the homesickness. Now, I get along with them with a fun school life.

Thank you for doing your homework, Linda!
