I usually get 4, two on paper and two by email which have not arrived yet.
Of the paper ones, one is really quite boring and in the third person, just a list of events arranged by month, totally devoid of any interesting details: my life would read:
May
We all spent a week in a cottage in Orforf
Little Glow has a good school report
Big glow goes on a school trip to Yorkshire
Glow has a job interview but just misses out
And so on. It tells me nothing, really. The second one is more conventional, but no real deliberate bragging. I do feel a bit jealous, they have much higher disposable income, live in a beautiful house and move in very MC circles (chair of the lions rotary club etc) but it's nice to see them do well.
Then around Christmas day itself I'll expect one from a more distant relative in my generation, and in the past that one has included quite personal details I would not have shared. About teens growing up troubled, issues at school. Marriage counselling, etc. I cringe and never mention it. My sister (below) also gets these and agrees.
My final one comes from my sister, chatty and full of stuff I know but I like to be reminded. Occasionally our family gets a mention
(like shared holidays) . This one is a kind of welcome review of the year for me, but others may well yawn as I do at the others.
And because I feel so meh about RRs I am not to inflicting them on anyone. The people we are close to know our news throughout the year and the rest don't need to know or don't care.
