maternal indistinct

Sometimes my puns are so obscure even I can't figure them out. By this one, for example, I'm trying to convey the intermittent sense of pseudo-motherhood I feel vis-a-vis N; though it might come across merely as an embarrassingly trite observation about all maternal impulses being alike.

Really looking forward to upcoming school holidays. Been Neglectful Sis since before summer trip, methinks. Repentant am I, and have started researching and planning - which can be over-stimulating. This sleepy ol' town still has much to offer, at least for the little ones.
