While researching Bible verses on friendship tonight (and if you ever need to find a passage of Scripture based on a phrase or word and your Bible concordance doesn't have it, I strongly recommend www.biblegateway.com), I found this really cool verse:
He who blesses his friend with a loud voice, rising early in the morning, It will be counted a curse to him. ~ Proverbs 27:14
Now I have to admit, I do find it funny when Bobby sings to my nieces or the Belarussian kids to get them up in the morning. And I don't mind when he sings to get me up in the morning, but I don't like the "exhortations." And to find that there's a Proverb about that is even funnier!
