..........I couldn't have cared less and didn't even offer her a peanut butter sandwich...............
Sorry to hijack but I think this is the first time I have ever known someone from that side of the pond to use this phrase correctly! This has made my day, it really has!
As for in-laws, mine are amazing. Not trying to rub your face in it, but they are both so lovely and made me feel like part of the family from the very start.
Can I suggest smacking her in the cheekbone with your elbow, or is that not subtle enough?
