Bring back consequences.  So you broke your leg.  One off. But you have students milking the system from broken nail, headache, stomach ache, sprained ankle, sprained wrist, sore back, hurting shoulder , they got all this from larking about and drinking too much and now they expect  a delay in their assignment or exam.     No responsibility.

I broke my ankle on a Saturday at 4:pm stepping of an uneven curb and wrote two exams on Monday.  Why , because of consequences!!!!  I am sure if my foot had a bone protruding it would be different or if I whined and whinged.,

How come today  so many people a feeble, snowflakey, wussy,  milky, whingy, whiney.  No intestinal fortitude.
