It is all about perception. What I might perceive as harassment, my father may perceive as encouragement. Because too much encouragement can be irritating, try t o balance out the time you spend with family. For instance, offer your assistance to the chef by running to the store for last minute items. Or, go on a movie run.
Children can also provide a needed distraction from family tensions.
If none are present at your function, borrow a neighbor's. Take the kids. Leave the house. Do not pass go. Head straight for the park, and swing your stress away.
