We are having a birthday party at our house for our 3-year old. I sent out a general invitation saying we'd have food and drinks for adults and kids and come over and have a glass of wine with us etc etc.
I got a reply back:
Thank you for the invitation to [Douglas' Kid]'s Birthday Party. [Invitees 5-year-old twins] would love to help [Douglas' Kid] celebrate her third birthday. Please count them in.
Maybe there's some code I need to learn, and maybe I'm reading too much into the way this note is phrased, but typically a kid's birthday at your home is not a couple hours of free day care, is it?
