<p>Growing up in my parents’ house, a lock on a door meant something was going on that should be hidden. i.e. bathroom, parents’ bedroom - you get the idea. So locks on children’s bedroom doors were not allowed.</p>
<p>I got an exception when I was 16 BECAUSE my little brother went in my room, destroyed my posters and my albums and put quarters between all the keys of my piano. I had to lobby for the lock and won with the agreement being that when I was home the door would be left unlocked. Little *@#$!!!</p>
<p>Since my girls were all closer in age, we really never had that issue. No locks on bedrooms.</p>
