To not go to London shopping

[Molly2008]

So my mum has a house full of relatives visiting from abroad. My mum has suggested that my cousin & I go shopping for a day in London and she will watch my kids.

Only problem is I don't want to go, can't afford to go. So AIBU to say no?

As per usual, OP disappeared and never did those who responded the courtesy of letting them know what happened in the end.

Maybe she went to london and got steaming

zombie thread but I find these kind of questions so weird - how strained must your parental relationship be if you can’t just tell your mum outright you don’t want to go shopping.
