If you were given gifts after hosting a wedding ceremony or party, be sure to send a thank you note to all who sent or gave you a gift.
This is important because they gave you gifts out of their free will. Therefore, courtesy demands you show appreciation by sending a thank you note after the ceremony to all you gave you a gift, and if possible to those who attended; one week interval is most appropriate for a short but beautifully written "thank you note".
Bottom-line: Do not take for granted acts of love such as this. Correct?
