Having played with Lihu and Kaili, I'm fine with you guys bringing your kids. I understand where Erik is coming from, but personally, I don't care as long as no one cares about me dropping the occasional F bomb, etc. (and to be honest, with Lihu and his son off in their own cart, I'm pretty sure they missed all my swearing....)
There were a couple of discussions with last month's outing: the children issue, guests, and asking for particular partners. I remember the kids one, and the 'asking for particular partners' one...guests I don't recall...
