Geunuinely interested in a bit of perspective! Younger daughter's birthday a few weeks ago. Saw the PIL - for the first time in six months - recently. FIL was asking how old she was as he and MIL had thought she was a year younger.
They had, in fairness, sent her a birthday card with some money in it, so I can't in any way claim they forgot the date. But I was a bit nonplussed that they didn't know how old their grandchild was! Am I being a bit picky, it is this another pretty definite sign of a total lack of interest on their part?
