Manners when you meet the parents
Do you remember those things your grandma used to go on about? Well, use them.
A few P’s and Q’s will make a huge difference in the world of first impressions. Be polite, say “yes, please”, “thank you” and a lot of compliments along the way about the food, the place and the people. See if there’s anything you could do to assist in the kitchen or the garage, and offer to be of assistance when they get up to get something.
These little acts of consideration linger in their happy thoughts. Don’t overdo it and try to pretend like you’re a programmed robot when you meet them. You may be nervous, but flirting outrageously with one or both of the parents is probably not the best way forward.
Talk to them, and project interest when you meet the parents. Your in-laws will like you more if you like them.
