Just that really.
No card. No letter. No phone call. No fb message even!
Just no thank you.
Her wedding was 4 months ago. Just had lunch today with another friend who was a guest, and she asked me if I'd received a thank you , because she hadn't. Both of us had sent cheques for £50 and gifts.
The cheques were cashed incidentally the day after the wedding!
She's a good friend (old school friend). Do we mention it? Or just leave it.?
