I forgot a PIN code of my tablet, so I couldn’t log in it. I have tried to use for the first time in a while, so I entered some codes I thought it’s right, but it weren’t working. Maybe I was confident to remember the codes when setting it, so I didn’t seem to note it anywhere. However, I completely betrayed myself. I imagined my thought patterns (my thought patterns should not be so many) tested as many codes as I can think of, but I couldn’t hit the correct one. In the end I couldn’t helped but resetting the tablet. I can’t understand myself in the past at all, even though she must have been me.
