The best part about using a computer is the undo button. No matter what you accidentally type or inset, you can always make it disappear fairly quickly. When I text a message or type a blog on my phone it is annoying that I can’t press the undo button. That was until Thomas showed me the light. He showed me how shaking your phone once causes a screen to appear saying cancel or undo. There is an undo button on the phone! This has been a Farley’s Castle life hack!
