3, 3, 2, 2, 3. on the 4th puzzle while looking for differences, i accidentally touched number 0 on the laptop's keyboard that it went back to the beginning of the video. so i estimated what time where i was last left off and i kind of lost sight of where to continue looking at the puzzles to find the remaining 2 differences. i did find the 1st differences seconds before i accidently touched the laptop's numeric keyboard. beside, i am not sure if i can find the 3rd difference even if i didn't accidently touch the keyboard number 0. overall, i got like 11 hours of sleep today which is more than enough which i like. combined with yesterday's afternoon where i took an hour nap and nearly another hour half awake, half asleep, i got like nearly 13 hours of sleep total. overall, i got like 4 hours of oversleeping which i don't mind at all. i rather over sleep than not getting enough sleep any day. i feel fully rested today and i am very, very happy.
