     Last winter vacation, some of my classmates decide to
travel with their friends, while I chose to take par-time job
to gain experience and earn some money. I learned from his
teacher that a nearby company was looking after students
with good handwriting to write address on envelope. The
pay were 10 cent per envelope. I headed for the company,
feeling sue I would easy finish 300 envelops in five hours and
to earn the money. Actually, I only finished 200. Now, I
fully understand how hard is to earn money. Getting out
of the classroom is indeed necessary for we all.
