to expect more than a text message as a thank you?

[DaydreamDolly]

I am willing to be shot down here, am just interested in people's opinion's, perhaps I'm old fashioned.
In the past month, I have bought 1st birthday presents for 5 children, and attended all their parties where by you never get to see them open the presents, you just leave them behind.
Anyway, I have received, to date, 1 written thank you, 2 text message thank you's (round robin ones at that, not personal ones) and have had nothing at all from 3. Not even an acknowledgement that a present was given.
I just feel a bit like no one really appreciates presents anymore in the throw away society we live in. I'd just like a little thank you note really, a text is a bit impersonal, but to have had nothing back whatsoever from 3 has got my goat I must admit.
Am I being unreasonable? Or is it just good manners?!

If someone says thank you whether it be in a text. written or just as your leaving it is still a thank you.
If someone does not say thank you at all then i do get annoyed myself as i am not that way and would always say thank you as i was bought up that way.
I also do not like when you ask children to your childs party and you do not get any reply what so ever from the parents.Then they ignore you next time they see you like they are avoiding you, now that is annoying!

A thank you for a present is always good manners, preferably by card or phone, but email would be OK. Text not great but better than nothing of course.

I think it's good if presents are not opened at the party. It avoids comparisons and allows more time for the party itself.

If presents are opened at the party and you thank the giver at the time, then no further thanks would be strictly necessary but it would still be a nice gesture.

However if presents are opened afterwards, then thanks should be sent for the specific present (even if the child said thanks for the unopened presents at the party).

Generic/round-robin thank yous are a bit lazy. Far nicer to receive a hand-written note thanking you for your specific gift, even if it's only a one-liner.
