As title.
Invited 3 school friends over for lunch next week end.
First friend texted and said they are looking forward to lunch and could they bring their adult daughter too ?
Then this morning another girl phoned and said she has family visiting and can she bring her mum?
2 minutes ago the 3rd friend phones to ask what time we are eating and could she bring her kids aged 14 and 15 ?
Is this normal?

Cancel the whole thing. They are all CFs

Bizarre behaviour.

Are you all in a WhatsApp group? If so I would put a message in the chat saying ‘OK , thanks all for your messages. It seems you all have family with you at the moment and I can’t manage 7 guests so it looks like it would make sense to rearrange. Who can do this if that date?’
