a tactful way of asking

[beastmonkey]

we got married a few weeks ago (hooray) we came back from the honeymoon yesterday.

whilst we were going through the cards/gifts we noticed 3 people hadn't given us anything (card or gift).

now i am not saying that they ought to have given us anything, but what i am concerned about is, that of these 3 people:

1)all them rsvp'd before the wedding (showing they know the correct protocol)
2)all are friends from uni days (so would class them as immediate friends)
3)one of the 3 has sent a thank you card to my parents in law.

the thing is all 3 were on the same table and i wonder if they left the cards on the table and they went missing.

my problem is this, how do i tactfully ask them if they did indeed do this, as obviously i need to send a thank you for any gift/present, but if i don't know that they left anything i can't send a thank you note and obviously when one doesn't arrive they are going to think me rude.

I don't really want to ask outright as this could cause embarrassment all round.

any help greatly appreciated.

If you are able to send a group email to all or most of the guests, you could send a casual message saying that you've had a great honeymoon.

Then you could tell a little lie and say that when you were sending out the thank you notes, there was one present where the label was missing, and you'd really like to thank the person. So, could the person who hasn't had their thank you note get in touch!!!

And although the email would apparently be to all the guests, you could in fact just send it to the three people by putting their address in the blind copy line.
