Here are some of my tests when faced with a dilemma. “Worst” test: What’s the worst that can happen if I do? What’s the worst that can happen if I don’t? “Reversibility” test: If I do it, can I undo it? If I don’t do it now, can I do it later? “Time spent” test: When I come down to my last days and hours, will I wish I could have this particular time back?—was it worth the time out of my life that I spent on it or not? “Pizza” test: Is it worth more or less than the cost of a pizza? How many pizzas is it worth? “Relief” test: If I decide not to do it, do I feel disappointed or relieved? “Feelings” test: Will someone be hurt by my choice? Does it matter to me or not? Apply as needed. Oh, yes, there’s also the Fluther test: what do the Flutherfolk say? In this case, and in your place, I might just tender my regrets and say I’m not feeling up to it. The “Relief” test would tell the story. Let them go ahead and spoil the conversation at the shower by making your bedbugs a major topic. How many times do you feel like repeating “I was afraid it might be bedbugs, but now I really don’t think it was”? And finally, here’s what you said: “I have zero interest in going to this thing.” Your own answers are always the best.
