A family member is invited to a wedding, forwards you their invite via email and keeps following up to check if you’re going to the wedding as well.

The more you think about it, the more you realize that you never actually received an invite yourself. The forwarded invite has your family member’s name on it, not yours.

So you contact the bride/groom to ask them when the wedding is and to let them know that you never received an invite and that they should tell you if you missed something.
