Imagine finding out that your daughter-in-law, whom you have been helping financially along with your son (her husband) has been saying horrible things about your family on an online forum?

This week’s problem, submitted to Dear Prudence, appears to be quite a tangled web, but Charlie thinks the problem is pretty simple to fix.
