You may have experienced a situation where you want to share something with someone but don't know who to contact. Or you may have had a good experience with someone but feel awkward because you don't know how to thank them. Or you may have had a bad experience with someone and feel sad. All these feelings can make you want to avoid saying goodbye to someone. But it doesn't mean you have to be rude and cold. You can say thank you to the person in a different way. It may be in the form of a gift or a card.
