Had a real issue with MIL this weekend over fairness. We were over with our DDs and their three cousins were also over. At the end of the day whe the three boys were off home, I caught her trusting £5 into their hands and asking them to 'SShhh!'. I assumed she wanted to surprise our girls with the same later when we left. The boys didn't Shh about it and told me and their cousins what they were going to spend it on. The girls didn't get their 'pocket money' and the Shhhing was obviously MIL trying to hide the fact she'd given them money. MIL is one of the wealthiest people I know and although I'd never expect her to give my girls pocket money, if she's going to give one set of grandchildren pocket money, in pretty much full view, shouldn't she give all of them? I felt really over protective of my girls and spoke with DH who didn't see anything wrong with it. To me it's really odd behaviour and it made me really cross, but maybe IABU...
