My mom had always had a rule which was, "you hitchhike, I spank!" I never hitchhiked, until I went away to college when I was 18 and hitched rides several times to the closest ( about 25 miles) major city. I thought I was now on my own and was no longer subject to obey my mom's rules, so in a phone call home I foolishly rubbed it in her face I had hitchhiked. I went home for Christmas break a month or so after the call, and a few days after my 19th birthday. When I entered the house, my mom immediately asked me "what happens to naughty boys who hitchhike?" I could tell where this was going and tried to talk my way out of being spanked, but mom would have none of my excuses. She turned me over her knee and administered 20 good spanks to my bottom. It was the worst spanking I had ever gotten, but it was effective, as I never hitched another ride, after mom spanked me for it!
