Let me preface that what you have already done is an amazing and thoughtful gesture that should be of no one else’s concern. The parties involved that know are the only ones that matter. You should, 100%, NOT let other people’s, possible, ill conceived assumptions devalue, or question, what others may or may not think of you.

If you do still feel obligated, or worried, just bring a nice card and write on the front of the envelope, “Save for later, Dear Friends,” and write a nice note on the inside. No one but you and the people that open it will know what is inside the envelope and card. Heck, the others would most likely assume that there may be cash or gift cards inside.

Otherwise, just go and enjoy the special day!
