DS is turning 7 and really wants his birthday at a place that has a minimum number of 10 (can be less but you'll pay for 10), and to be honest that's all we can afford.
There are 18 (all boys) in his class. Most have had whole class parties so far. But most are wealthier than we are.
There are 10 boys DS actually wants to invite. He really wants all of them invited and can't think of anyone to leave off.
BUT it works out to over the "half the class or all" rule
But we aren't leaving out just 1 or 2... And I doubt anyone will be counting up exactly who has been invited accurately enough to differentiate between 9 or 10... It feels a bit silly to tell him to cut out a friend he actually wants there.
...Is this acceptable?
