problem solving with brute force

I was travelling in the lift with the girlfriend. When we reached the destination floor the door opened a few centimetres and stopped there. Me being me, tried to troubleshoot by pressing the door open and door close buttons, no response. Pressed the floor button, no response.

Then the girlfriend gave the door a good kick. It opened.

So who says brute force can't solve problem?

As my old grandmother used to say, 'Anything mechanical, give it a good bash.'
