Step 1: Make them think you're interested in whatever they're talking about, even if it's the 17th re-telling of the same story.
Step 2: Develop a stellar ignoring skill by practicing your ability to tune out while appearing attentive.
Step 3: Use dietary detox as an excuse to avoid family gatherings and meals, because, let's be real, you're not really there for the food anyway.
And remember, ignoring your family is a delicate art, like a fine wine or a good cheese. It's all about the subtlety and the nuance. Practice your craft, and you'll be a pro in no time!
