What git decided that!

I am well and truly fed up with having massive bumps and bruises half way down the front of my thighs. Have I been drinking too much and falling down the stairs, maybe I have been doing some exciting dangerous sport, or possibly the kids have been giving me a good kicking.

Nope I have to say that the cause of my injury is those nasty sneaky stair gates. Every now and again I walk whack bang straight into the corner of the open stair gate. This hurts more than seems proportional to the actual injury, and the bruise always seems to come up so much bigger than you would expect for a little bump.

Did some evil mum hating person sit down at their computer to actually calculate the average height of a mum, and then spend a long time working out the ideal height for a stair gate to cause the most injury.

Do you think I can sue the person that first set the standard height for stair gates?
