Holy Thursday, Confession and Sin

Remember we were marched over to confession every Holy Thursday? One time I told Sr. Ignatious that I did not think it was fair that we all had to go to over to confession "every single Holy Thursday". She asked why and I said, "Sister, I didn't commit any sins this month". She pulled me by the hair in the hallway and said "Get in that line, Young Man!"
I thought to myself "I guess I'll just have to make them up again"...."I had unpure thoughts three times, I was unkind to my neighbor twice...I disobeyed my parents...."
