Personality change pinpointed

My Mom told me she knows when I changed.  I was in the 10th grade in high school and she told me that is exactly when my personality started changing.

I used to be an introvert.  The biggest introvert anyone ever knew.  I was a wall decoration who would cling to the bricks of the outside of woodshop during Nutrition and Lunch.  In the group of friends I had I was the most quiet.

In the 10th grade I joined the wrestling team and I was to become familiar with the most extroverted people of the entire high school.

Little by little they took me under their wing and trained me.  They directly trained me in wrestling skills and maneuvers but indirectly showed me the ways of socializing.

I was never really that good in wrestling, might have been due to my introvertness.  I was always so timid and shy that I let that get in the way of winning matches, but I guess now that is a thing of the past
