My now two-year-old daughter is discovering lots of new feelings. Her favorite seems to be unbridled rage. There's yelling, throwing herself on the ground, hitting, biting, and plenty of other activities that her mother and I refer to as "counter-productive." 

That this is normal for a toddler (this age isn't called the "terrific twos") is little comfort. Getting her re-focused, thankfully, hasn't been too hard yet. 

As we get older, we're better at controlling our rage, but it's often still lurking under the surface. That lurking rage is a distraction in bridge. So when I hear people say "Ugh I hate declaring 1NT" or "I can't believe [partner] forgot our convention card, AGAIN," I know I'm about to witness some subpar declarer play.
