DS has been invited to a party in August, which I accepted. But now DH wants to take DC to MIL's that week and the party is on the Friday. It's the only week DH can go so it's then or never, or he could go Mon-Thurs instead of Mon-Sun. But it's a 6hr drive so two days will be spent travelling. I feel a bit a shoddy cancelling as I think it's a bit off to 'have found something better to do'. But equally DS doesn't really know this boy so I'm not sure what to do. WWYD?
