His assessment of the situation was spot-on.
Do not go chasing after your three year old niece when you're playing outside, hollering "I'm going to catch you!" to make her squeal and run away. When you do catch her, she will drop her weight like a stone and make you loose your balance and trip. Your efforts to protect her in the fall will succeed. You, however, will not be so lucky, and will face-plant into the side walk. Fixing the tooth you broke will be expensive. #LFMF.
If you ever get a really good, fast spin going in an office chair, don't let go of the armrests thinking you can sit back and let it wind down. The momentum will send you careening into the wall of your cubicle, from where you will dizzily spin into another coworker's space, collapsing heavily onto their lunch. There will be a fairly large number of people demanding explanations. #LFMF
