When my first son was a less than a year old I noticed a spider hanging down from the light fixture right above his high chair. I went and got the dust buster and vacuumed it away before the spider could drop down and scare him. What didn’t occur to me was a vacuum cleaner running full blast a few inches from your face is much scarier than that spider would have been. Years later he is still frightened by loud machinery, dishwashers, public toilets flushing etc. Good job dad.
