In the years you've been dating, you and your significant other's parents have met on more than one occasion, though they haven't spent all the much in the way of quality time together. Now that you're engaged, the time has come for them to get better acquainted.
Prior to the night of your engagement party, you plan a dinner for both sets of parents to enjoy. But after less than an hour together, it's clear to both you and your fiancé that they aren't having a good time. In fact, when it's over, both complain separately about how they don't like the other. You're both close to your families and need their help planning the wedding, so how do you handle this?
