Oh! The question isn’t even about locks at all!
It’s about privacy and whether children and teenagers should be trusted by parents to be alone in their room because they might get up to no good!
I’m kind of surprised to see a lot of these responses. Most of them seem to suggest that children/teenagers shouldn’t be allowed to go out on their own lest they do something wrong due to a lack of supervision. Is one better off growing as an individual through both success and failure or should they be overly-protected and never have the opportunities to do so? Seems rather obvious…
My view? Rather than not trusting your children (which is inherently messed up), TEACH them what is right and wrong. At least have a conversation with the children as to why or why not they may be provided with locks or not. It seems almost passive-agressive to simply not provide a lock due to a lack of trust. Children/teenagers won’t take anything away from that except “my parents don’t trust me or value my privacy”.
