On a need to do basis!

Aren't we humans funny - and I mean funny Oiiiii rather than funny hahaha (well that depends on which humans we are talking about). ahem - now I'll finally get to my point which is THIS - When nobody is responsible for us we gladly and easily take responsibility for ourselves. Case in point - Mum and Dad are away, we have washed up, put the rubbish bin out, cooked, woken up ON TIME, done the washing (well my brother has) and all sorts of other stuff which would normally induce nausea, migraines or emotional frustration of great proportion. Why don't we do these things as naturally when we are under the authority of others???
