In any social situation. be it completely new or an existing one you prefer to avoid (country, town, job, local bowling league, visiting the in-laws) that has its own set way of doing things, short of personally starting a revolution to enlighten everyone into believing and acting only as you want them to, your choices are Adapt, Migrate, Mutate, or Die. Most people don't kill themselves because they don't like the local behavior patters, so this leaves Adapt, Migrate, or Mutate.
Adapting is the most straightforward. Minimize the amounts of interactions you find displeasing as much as possible and then follow the When In Rome motto for the truly unavoidable. When your spouse laughs at her fathers lame jokes, you at least grin. When grandma gives you a sweater so horrible that you plan to burn in the fireplace as soon as you get it home, you smile and say now nice it is. When the new company gives everyone a "surprise" birthday party every year, you at least refrain from telling the office manager (who thinks this is the best idea he ever had, and sadly it probably was better than all his other ideas) how unsurprising it is. Everyone does some version of this all the time. In a fair world, people who take 25 items into the 10 item express checkout lane should be subject to massive verbal abuse, but the general social rules usually limit most such interactions to disapproving expressions or a quietly muttered snarky comment.
Migrate. Think living somewhere else might be better? Move. Dislike an entire country? Don't move there. If there already, move away. Hate your job, cannot adapt or mutate? Start applying elsewhere. Supposed to go spend a week with the in-laws you can't stand? "I'm terribly sorry, but my work is sending me on a business trip that week and the next week two. Then I'll be busy for a month catching up on things in the office."
Mutation isn't always a conscious thing. You HATE the new mandatory shirts your bowling league makes you wear, but after all hints about what you think the perfect shirt should look like falls on deaf ears, you might eventually decide it's not as bad as you originally thought (alternatively, if you hate it worse each time, but wear it because you want to play, then you're just adapting). When Uncle Jack insists that everyone join in on multi-player solitaire (yes, there really is such a thing) and you hate it, you decide to study it more closely in order to try to end his winning streak forever. If you succeed, you might play just for the enjoyment of seeing him lose. When you finally get frustrated enough while studying Mandarin to start using bilingual Peppa Pig CDs to help expand your vocabulary, you've just mutated into a certified Lunatic.
