My youngest is a "button pusher" in more ways then one. Now-a-days, he usually just pushes my buttons with arguments, as to why I should pay him more money for just "being."
When he was little, though, he had a penchant for pushing physical buttons - usually the wrong buttons - whenever he saw one. Once when we took him to get his hair cut, he pushed the button on the computer that ran the shop's program for creating invoices and receiving payments. He managed to shut down their whole system and no one there knew how to get it back up again. We left the shop with the stylists frantically calling head office for help!! It was very embarrassing!!
Yesterday he was in the office helping me move some furniture around and today, I noticed that the button to lock the filing cabinet had been pushed in. The filing cabinet was locked! I had no idea where the key was! In fact, this happened once years ago and my brother-in-law at the time, whom I suspected had skills beyond those of basic carpentry, opened it for me.
Now I had to figure out what he had done. I tried a few generic looking keys - no luck. Usually when all else fails, I use a knitting needle, even this didn't work. Finally I tried a nail file - Voila!! It worked!! Ironically, the file was from a manicure set that said "button-pusher" had given me as a gift a few years ago, interesting.
Try this only, if you own the lock. I don't want to be accused of abetting any breaking and entering :)
Have a wonderful day!!!
