Your vows should reflect your feelings for your partner and the love you have. A lot of times sharing a funny story, or cute memory, can help illustrate your relationship/love to your guests. But when does sharing something personal become, too personal? It’s cute to share the story about how he helped you clean your room when you were sick, but maybe leave out the part where you kept pooping your pants. Talking about how the two of you “truly connected when you first met” is amazing, but don't talk about how that ‘connection’ was under the sheets.
