I definitely don’t feel like this about my mother! And I’m 99% sure she never felt this way about her mother, nor do my cousins feel that way about my aunts. So I guess your question would be why not? Never thought about it before, but now you’ve asked the question, mulling it over:
My mother is always pleased to hear from me and to see me, but there is no expectation that makes me feel guilty if it is a while between calls. So anytime I ring, she’ll say “lovely to hear from you” but there is absolutely no sub-text of “and about time too” or “why has it been so long since you rang”.
She is interested in and loves me and my kids, and always asks about me/them and genuinely cares about the answer, but she is also living her own life with friends and hobbies, so there is no sense that she is only living through us.
She will give suggestions or advice if asked, and occasionally suggest things, but doesn’t get offended if I don’t follow them.
Finally, she has an excellent sense of humour and is a fun and kind person, who I really enjoy talking to and spending time with. I like to think I’d want to spend time with her even if she wasn’t my mother but was an elderly neighbour or retired former work colleague.
Hope that helps!
