Bunking or cutting classes is one of the experiences that enrich a student's life..although it is a very wrong thing to do. However, the thrill and excitement you get when you run away in stealth is memorable and you'll probably narrate it to your grandchildren (not a very good example to set).
I too have bunked on numerous occassions : to eat, watch movies, complete record work and once, simply to sleep..which could have been accomplished in the last bench of class..hehe.
