| Since you know they're not going to be happy, I would start out by stating that you've got some very good news, and that you know they'll be as happy and excited as you are. Then let them know that you're going to be parents, and when.
If they respond with negativity, then be prepared to leave,letting them know that you know they care for you, but that you are BOTH happy about this, and that while their advice is appreciated, their negative attitude isn't. |
