Background is MIL claims to not have a lot but has paid off her mortgage, works part time and lives what I think of as a very nice lifestyle. Lots of restaurants, nails done, gym memberships etc. she does claim to struggle but she spends a lot of luxuries. She is on her own.
She wants to meet us for various days out which she suggests- fancy things like kids theatre days or theme parks but thinks it's categorically wrong for her to pay anything towards this. I'm talking about paying her own way not paying for us or DC. She won't even pay for a drink when out with us, she acts like another child who doesn't have access to any money.
There is a huge backstory to this and her believing DH should provide for her. She says all her friends have lovely sons who book all kinds of activities for them to do with their grandchildren and she always makes sure to tell us that the grandparents are never expected to pay a penny!
My parents are the opposite and want to treat us all the time. How do we navigate all these treat days MIL wants to do without burning bridges and being rude or coming across as mean? Or is it normal to pay for a grandparent every time for things like this?
