We received a number of floral arrangements from groups of adult siblings. For example: my deceased aunt had 3 children who are all in their 70's, the card with the flowers listed all their names included the living spouse of a deceased sibling. Should I send a thank you to each one, or only the first one listed and that person is expected to pass on our appreciation to their siblings?
If this was an aunt and her adult children, I'd feel comfortable only sending to the aunt, but since all the people are of the same relationship and all are older (not 20's living at home) I'm not sure what to do.
For the flowers, I would reply to the person who actually had them sent and paid for them, not all the names listed.
When my boss' wife had passed away this past summer, he included not only those who had sent flowers, but also to everyone who signed the guest register at the funeral home.... and to those who had sent him cards afterwards. That was a lot of thank you cards, so my boss got boxes of sympathy thank you cards from Hallmark and inside each card all he wrote was "Love, Bob".
