I've exchanged Xmas cards for years with an old school friend- knew her from being 3! We were best friends up to secondary school, then she married young (19) and I moved 300 miles away.
We didn't really keep in touch partly because I rarely went back to my home town and if I did it was only briefly. I've met her about 3 times over 20 years, during which time she's divorced and got a new partner.
Anyway, last Xmas gone we exchanged cards and she added a note saying she hoped my parents were okay - they used to be good friends with her parents- because she doesn't hear anything about them now ( due to her remaining parent dying a couple of years back.)
I decided to try to resurrect the friendship- wrote a card to her last week and said thanks for asking about them, gave a few details and also gave her my email address saying maybe she could let me have hers and I'd let her know when I was visiting next and maybe we'd meet for a coffee.
Not heard a thing. My email address was a bit scruffily written and I wonder if it wasn't quite legible, but because of my work she could easily google and find me and my contact details online.
Just leave it?
