It’s bittersweet to be so happy for someone who is moving on, and yet so sad to see them leave. It doesn’t matter if they are physically leaving, or moving ahead in their life in a way that means you will not see them as often. Let your happiness for them override the sadness. It’s okay to be sad and to miss them – feel those feelings. Just don’t let your sadness overcome being happy for what they have found and all the good things to come for them. Let them know they will be missed, and that you wish them all the good that the Universe has to offer.
