I told the entire school that I knew how to solve a rubiks cube. It got way out of hand. I later had to spend hours per day learning how to solve a rubiks cube. Fast forward 5 years later to now. I enter competitions for cubing. I can now solve a rubiks cube in under 25 seconds.
How long did it take you the first time?
The first time I solved it, it took me two hours.
Sometimes we have to fake it to make it. At least you learned a new skill after lying.
It motivated me to stretch beyond my comfort zone.
Sometimes white lies can be constructive. I like your creative use of positive fibbing.
