So you got hit by a lorry...

It happens.. Accept it. Accept the blame too. Dont blame it on the driver.. you were the one standing in the middle of the road thinking noone would hit you. Assess the damage objectively. You lost an arm? Well.. it could have been worse.. But the point is, that its a great lesson! Learn from it.

Think of Stephen Hawking… and you are complaining about a lost arm??? Stop insulting your intelligence and MOVE ON. You can still do great things! And remember not to stand in the middle of the road next time. :)
