The Huffington Post suggests waiting before you open your mouth - this means that when your relatives are making comments, hold your tongue to keep the peace. Practicing this leading up to Thanksgiving might be worth your time.
It's also important to avoid taking your family's comments to heart. We all know people who are guilty of saying things they don't mean, so take their remarks with a grain of salt to keep yourself from becoming stressed. When conversing with others, don't concern yourself with getting an "eye for an eye" when you make your own statements.
If you're afraid of confrontations ruining your Thanksgiving, consider speaking to your psychic advisor for advice. A tarot reading can let you know what you're in for once you're in the same room with your family. This can help you better prepare for the future.
