I have a funny meet the parents story...when I first started dating my boyfriend we were doing long-distance as he was studying in England at the time. His dad lived here, so when he left to go back to school, I got a call from him one day asking me to have dinner with him and my boyfriend's stepmom! I was SO nervous...felt really weird, I mean my boyfriend wasn't there. But they invited some other friends so I wouldn't feel pressured and they are very laid-back people and it was great.
I have a funnier story though...my boyfriend's dad and my mom had met before. Why is this funny? Because they met when my boyfriend and I were 12, they are from England and Portugal, and they met in a conference in The Hague. They got on well and my mother gave his dad a little souvenir of portugal (a little miniature silver caravel). So, when we had our first parents meet parents dinner, his dad suddenly goes ..."aren't you...?" and we were stunned to know we'd had each other's phone number from the age of 12! (we were 22 when we met)
