Congratulations! A whole new set of relationships for you to forge, including the one with your son-in-law. Just a little word of warning: remember that all these new people don't know you well yet, so make no assumptions. Leave them room to thrive and have different viewpoints that may not match yours. Err on the side of love, and err on the side of caution. As my mother used to say every time I thanked her for kindness to Nessie, she would retort: "Mother-in-law is a heavy and tainted name, I have to go out of my way to show kindness because it may not be obvious to others what I feel".
