OK - deep breath
He's had a mini stroke. Hes a bit young (44) but he's physically fit and may never have one again.
He can't drive until he's seen a stroke specialist (sprry can't remember the exact name) this afternoon. He's getting a taxi back to school and his colleague will take him. he doesn't want me to come yet until he knows more. His parents were due to visit tonight anyway so they could take dd to school tomorrow.
Next week we do have the situation on Monday that dd has a biology exam there on the morning and ds has a dance exam here in the afternoon.
He repeatedly told me not to panic.
