Bi-Polar manic depressives or children.
Sometimes one bad thing can ruin their day or throw them into an ever wondering stupor of what went wrong.
During times of deprevation (like now) they are known to lash out, turn sullen and walk around in a stupor.
They tend to have a one track mind and refuse to let anything get in their way.
Show careless reguard for putting themselves in danger.
