The dog ate your license. Or it was stolen. Or it was burned in the fire that ate Gramma’s house. Just go to the DMV, and bring proper forms of identification so that they can verify it’s really you. There may be a fee to replace the license, which kinda sucks, but maybe you shouldn’t have lost it, ya know? What? It wasn’t your fault? Sure, sure. They’ll hand you a temporary license, and then mail you a real one later. Piece of cake.
