Part of living and growing up includes making poor choices, and hopefully learning from them. My life sure has included plenty of poor choices.
That said in my family we are pretty frank and if one of us acts like a fool someone will call you on it. Its not uncommon to be like "Are you freaking kidding me? What were you thinking" and then we move on. I enjoy the fact that we aren't artifically polite and we know the love doesn't waiver.
