Taking decisions: We know, and we have seen, many in-laws that are very nosy and tricky wants to get into your matters and problems. That can certainly be a little irritating, but it's not harmful. Whether you're discussing buying a house or having children, your in-laws contribute their two cents as if it should be the deciding vote in your decision-making process.
HOW TO DEAL: Keep a smiling face, maintain peace, nod your head at their views on the matter, and do what you and your decision anyway. Some time explain your views to your in-laws that, while you value their thoughts and opinions, you now need to make the judgment you feel just the two of you need to drive.
