So true. 100% of the time, with every moment, watch your words parents, please! Don't worry I'm a parent too, been there and lived through it. One poorly chosen sentence can burn itself into a kids' brain for life.
The truth about everyone... I think it's super important to remember this when having a conversation with a best friend, a coworker, a client, or a stranger on the street. You have no idea what's happening in their life and no right to judge for anything. Always be respectful, and full of love and you will never go wrong. :)
