My SIL (DH’s sister) has always been as tight as they come. Expecting hospitality but not giving it, implying that we should share certain privileges we have and other general CF behaviour. She’s also always made sure any gifts for DC have been the cheapest thing she can get her hands on.
Except now she seems to have changed her tune. Birthday present for DS was a very smart shirt from a well known brand (she doesn’t do brands). Is this the new normal? Can a leopard change its spots?
