Goose, Do you ring her?
Two of my children lived fairly near, and contact me about once every week or two (not religiously) to keep updated. My older daughter lives at the other end of the country, and hardly ever phones me, so I phone her every 3 or 4 weeks at a time when I think she wil not be up to the eyes in children, work, sport, and socialising with friends. We sometimes talk for an hour, on every subject under the sun, and at the end of it we ring off with her saying she will phone me next time, yes really. I reply that I will believe it when I hear it, we both laugh and that is that. We enjoy the contact, and I never ever criticise her - I know that they have many friends, the children have busy lives and have to be delivered here and there, she has a house to run, a job to go to and a life to lead.
I came home late yesterday evening from a Christmas meal with the other two parts of the family. As I sat on my own, she rang me and we talked for ages. She had spent an enjoyable but hectic day with inlaws but found pleasure in ringing me too.
If I had been critical in the past, and piled on the guilt for not phoning, she would see it as a duty and a penance, and interrupted her own fun saying "I must go and phone Mum or she will be miserable".
Whenever my parents used to visit my grandmother, she would comment on how long it had been since we had last been there, "Haven't seen you for a fortnight/week/whatever!", which did not make it a pleasant experience. I swore then that I would make my children want to contact me, not fear my comments if they did not.
