MawtheMerrier From the age of 11, away at boarding school, on Sunday evenings I sat down and wrote home, knowing that at home, wherever that may have been at the time, my parents were each writing a letter, one to me and one to my sister.
I continued this through my university years and the early years of my marriage, when we did not have a phone.
When we got a phone, I started ringing every Sunday evening, time varied, I kept that up until my father died in 2007, well into his 90s.
When our children left home and after the unsettled years settled down to their chosen careers, we started ringing them on a Sunday evening - and still do. DS is less regular because of his work, but every Sunday evening, we ring them both, still.
