I also enjoyed this section of Letter 60. At a time of bereavement, Jane copes.
I think Jane understood the consolation of tears, letters intermingled with amusements. She kept the boys busy and interested with diversions and small expeditions.
Agree with you; to display such caring and sensitivity to her young nephews, she must've liked children-Whilst she wrote she was aware George was making paper ships and Edward intently read his book. I love how her letter pins down such a cosy moment.
