Like the crackling of thorns under the pot, so is the laughter of fools. This too is meaningless.
Lately I have been having a struggle with the entire book of Ecclesiastes. But this verse makes sense to me. When people use laughter to be dismissive, or hurtful or disrespectful, nothing good can come from it. It is ultimately meaningless, and signals that the one laughing has ceased caring. This is a misuse of laughter, and in the scheme of things, really is useless.
Lord God, May I never laugh at the expense of others. Laughter is a blessing, and I need to always remember this. Amen
