I guess I should clarify about what it is that bothers me. I had a conversation with the co-contributer concerning my feelings about being anonymous. We talked at length about why I feel this way. At the conclusion of this conversation she agreed that this would be an anonymous gift. But, consequent to that, she delivered the gift in such as way as to allow the recipient to be able to know who had left that card. Then, when the recipient asked her about it, she took total credit for the whole gift. I'm left feeling that the co-contributer was dishonest in her promise to me to keep it anonymous, and also was dishonest with the recipient when she identified herself as the giver. (not to mention, she had said the gift was a "blessing from God"...but then took credit for it as a blessing from herself...but that's between her and God, not me).
In the end, I would give the gift again...anonymously. But, in the future, I will probably not go about in this way.
By the way, the fees are to a public school. It certainly isn't the equivalent of a private tuition fee, but also, it was no small sum. The money came from our emergency fund actually. That fund will be replenished over the next 6 weeks or so.
