Hints & Tips
What are the best birthday wishes for my in-laws?
In-laws, by definition, are related to you by law...not by choice. This immediately puts you at a disadvantage when it comes to writing in-law birthday wishes for them. Why a disadvantage? Because you don't know them as well as your own family, and you may not even like them very much either.
So what are the best birthday wishes for your in-laws? Full disclosure: I have a great relationship with my in-laws, so the in-law birthday wishes I've written on this page are based on the bad experiences of others and some information I scraped together from an excellent article on in-laws.
With in-laws, you need to acknowledge a certain fact, no matter how generous you are with your judgement of people: You don’t pick your in-laws—circumstance does.
This fact has ramifications, namely that your in-laws can be as sweet as honey or as sour as lemons (I politely refer to the "lemon" variety as “outlaws”). Chances are you have a mix of sweet and sour in-laws.
So when it comes to birthday wishes, it's very tempting to tell you to tread softly and take the safe route, sticking to the typical “happy birthday” message. Why? You often can’t go wrong with it (“often” because sometimes you just can’t please your in-laws).
Of course, I said I was "tempted" to suggest this path. I never suggested that you should actually take this route. In fact, I'm more tempted to recommend another direction altogether.
Then, what route should you take? Put simply: you should choose your birthday message as if you were selecting birthday greetings for your own family.
How so? Below, take a look at nine recommendations that come from the article (not all 25, mind you) and my tips for writing the best in-law birthday wishes based on these suggestions:
Common courtesy still applies: If you absolutely detest your in-law, you should still choose to write a nice (yet generic) "happy" birthday wish as a courtesy.
Extend grace to your in-laws: Be graceful with your birthday greetings, even if you harbor ill feelings. Once again, choose to craft a "happy" message.
Treat your in-laws like family: With your own mother, you would probably choose a birthday message that reflects her personality. Don't do anything differently with your in-laws. If your son-in-law, for example, is the sentimental type, opt for a son-in-law birthday wish that's sentimental. If he's an inspirational kind of guy, take the "inspirational" path with his birthday greetings.
Be true to yourself: Create a birthday verse that expresses your thoughts about your in-law (keeping in mind the three suggestions above, so no bad thoughts).
Focus on the positive: If your mother-in-law, for instance, is a generous person (but is nasty in every other way), highlight this positive strength in her birthday wish.
Don't pigeonhole your in-laws: Get over your first impressions of your in-laws and try to get to know them better, so you can write birthday wishes that focus on aspects of their personality you respect or even like (which makes following the advice right above so much easier).
Swallow your pride and let go of your grudges: If you can follow this lovely piece of advice, you will be able to act upon Recommendation #4.
Become their friend: Being friends with your in-laws will allow you to create friend-type birthday messages, always a nice way to go.
Find a respectful way to express yourself: Basically, showing some respect to your in-laws will enable you to benefit from Recommendation #1 or #2.
One more thing: don't worry about creating the right message. Ultimately, you just need to write in-law birthday wishes that make the birthday boy or girl feel special and make you feel good expressing them.
