got told this joke at school today, came home told me mum and she laughed her socks off

Woman turns in for work just after her mum dies, she sitting there in the canteen cryin & the manager asks her whats wrong,
my mum's just died she says,
Oh dear says the manager, do u want to take the day off ?
No she said i'll be alright.

So the next day she's in the canteen again crying, the manager again comes to her and asks whats wrong,
she replies,
i've just phoned my sister and her mum's died as well
