Family nonsense. However. My sister's daughter is turning 21. My sister and brother in law have arranged a rather nice and expensive cocktail party for her. So far, lovely.My bro and sister in law are however considering not going as it is a non child friendly event. It's a cocktail party. Bro and SIL are miffed at the exclusion of children. Refusing to attend at the moment. Not like my brother at all, but that is a different subject. If my Mum caves in and babysits, therefore missing the party, will be angry. Love my SIL! But I Think this is unreasonable. Am I right?
