MIL had only 1 son born at the start of WW2, she was thrilled when I gave her 2 lovely GDs 3 years apart. DH & I were not well off as we had lost 50% of our income when I had to give up work during the 1st pregnancy, but the girls were always well dressed as I sewed/knitted many of their clothes, using fabric bought in charity shops (1 'adult sized posh frock' easily made 2 child sized party dresses, a large man's shirt became 2 pairs of dungarees and so on.
However, every Christmas, on Christmas Day, MIL gifted them matching, very expensive Party frocks and posh winter coats, with the expectation that they would be worn on Christmas day. Of course all the Christmas parties (Playgroup, Sunday school etc.) had passed and in November I had already bought Winter Coats for them so apart from visits to Granny, these items were never worn.
This is all nearly 50 years ago but as you can tell, still rankles to this day.
