I have the problem wherein I have a permanently blocked nose and I am a small person. Consequently I have a kind of squeaky, nasally voice. The problem with the eventual inlaws lied in that they are both schoolteachers. His dad, not so bad. His mother - EVERY TIME I talk to her on the phone, she talks back to me like I'm four. She doesn't do this when we are in person (not always, anyway) so I assume that she just hears the higher pitched voice and regresses back to the classroom. But do you know how galling it is, at the age of 25, to be spoken to like a four year old? Seriously, each time I want to stab her with a fork.

Childishly, I get revenge by calling her by her first name continuously, which always throws her. ;-)

Seriously, hon, remember, it's YOUR wedding and his parents are just minor inconveniences. It may turn out that they are as shy as you are around them, and so they just come across as standoffish - maybe that's how you seem to them too. Sometimes shy people seem snobby rather than shy. Plus, remember, you may never win with them - after all, you're taking their little boy away!
