A) Are Tostitos not a proper dinner? I wasn't aware
B) I do the same thing with my bedroom clock because I can't deal with mornings and have snooze button addiction. The clock is turned back one hour so if I wake up and panic that I will be late, I go into the kitchen and realize the real time (but by then it's too late). Unfortunately, after a month or so, my brain adjusts and I can't fool it anymore. I just hit the snooze for longer periods.
Then again, I'm only having... What am I having? Oh right - nothing - too busy fixing my car.
