Were you ever given corporal punishment at school. What for? What form did it take? Did it have any lasting effect on you (good or bad)?

I used to bunk classes but every time I could manage to escape somehow. But that was an awful day. Nearly 20 of us bunked the class. Our teacher knew it and finally caught all of us red-handed. We were asked to kneel down in the corridor for a long time. Then came our conduct teacher. We screamed to see her. She ordered,"Stand up boys face the wall and pull down your pants and underwears. The girls uplift your skirts and face the walls.Then pull down your panties." We could hear our heartbeats. She started with the first boy in the row. It was an wooden ruler. Just with the first two blows he started crying. But no use. She went on spanking one by one. My turn came a little later. I was holding my skirt with hands and my panty near my ankles. Then came the harsh strokes of the rulers on my bottoms. I screamed in pain. She first spanked my left buttock and then the right. Then when she thought it was good enough she went to the next girl. This was first session. In the next session all except five of us were spanked. This time the spanking was harder and 30 strokes.
Our friends left and she ordered us"Put on your undergarments and follow me." We shrieked. This time to her room. Our legs were trembling. Once we reached her room we were asked to pull down our panties and underwears once again. As we were repeatedly bunking the punishment will be harder for us. She took a cane this time and spanked our bottom so hard. One of the boy's bottom started bleeding. Our bottoms were nearly roasted. But the icing of the cake was left. She then came out with a belt. This time she belted our bottoms so hard that it did start to bleed. It was at this point that she stopped."Hope you will remember the belt before you bunk the next time. Once more I catch you bunking I will skin you alive. REMEMBER. "
Oh! I could not sit properly or even sleep for a week nearly. I hated our conduct teacher always. But I never bunked classes after that.
