Whoever is patient has great understanding,
    but one who is quick-tempered displays folly.

I’m not really sure what I can say to enhance or explain this proverb, for it seems pretty obvious to me what Solomon is getting at, other than to say that it reminds me of the time when one of my kids asked if she could go somewhere, and couldn’t shut up long enough for me to say it was OK. Apparently, she knew something that I didn’t, and was so anxious to cover it up that she launched into a tirade about how she never gets to do anything, and she hadn’t noticed I said yes. She went on and on, and my “yes” became “no”.

I figured it out later, when I discovered that she hadn’t done something she was supposed to have done, cleaning her room or doing her homework… I can’t recall exactly which it was at this point, but the folly of her impatience lost her the “yes” she would have gotten that day…
