A school mum's just sent a message inviting DD to her DDs party. The only thing is I wonder whether she meant to send it to me. Her DD is in the other class, coincidentally DD's name was on the other class list at the start of the year though they aren't actually in the same class. We've never had a playdate in the past. Her child is really lovely and our kids occasionally play together at school but it's not like they are best mates. Any advice on how best to phrase it to check whether she actually meant to send the message to me or not? Please help...
