Mum left 'hurt' and 'angry' after grandma sends granddaughter home with an invoice

A mum has written a candid message to agony aunt 'Ask Amy' of the Washington Post. The letter in which she confesses an issue she's facing with her mother has been shared hundreds of times online.

"I sent a cheque for $300 to my mother to cover my daughter’s expenses during her visit. Upon my daughter’s return, my mother sent me an invoice for $475.50 for additional expenses, including the cost of gas to and from the airport to transport her (45 minutes away), train tickets to go to the city to a museum and the cost of the museum admission. It was an itemized bill."

"This is hurtful, as this past winter my mother came to live with us for four months and we paid for everything, including a nice vacation to an island over Christmas. (Neither of my siblings has a relationship with my mother because she is petty and doesn’t respect boundaries — like a $300 budget)."

"Now I feel she has taken advantage of my generosity, and I don’t trust her to spend time with my daughter because it is just too costly for me (financially and emotionally)."

'Ask Amy' suggested that the best course of action may be to 'express your concern directly to your mother.' but others on the internet weren't so sure...

How would you deal with this situation?
