There has been much debate as to who’s the most irresponsible adult on OUAT. Is it David who blatantly had a public affair? Is it Regina who is at the very least a little emotionally abusive toward Henry (in at least the incident involving tricking Emma into calling Henry crazy in front of him)? Is it Mary Margaret who thought she could actually escape jail? Jefferson who was smart enough to know the two go through, two come back rule and still trusted Regina? Or was it Archie who listened to Regina and ended up spurring Henry on to go into the mine?
All acts of stupidness and irresponsibility doubtless, but there is one person above all who is probably the stupidest and most irresponsible in the ENTIRE show.

The idiot cab driver who drove the TEN YEAR OLD BOY, accepting a woman’s credit card!

Honestly, did Henry really look like a Mary Margaret? That guy could have lost his job and be sued if she wanted to press charges.
