Bicycle detail

Received an unexpected invite to dinner while on a quick evening ride, changed direction headed to the restaurant. Unfortunately I did not have any gear with me, including a lock, so my parents and I waited for window seating to ensure we could keep an eye out on the bike. We sat in a booth on the other side of the window of where the bike was leaning. Nevertheless the bike disappeared within what seemed like seconds. I realize my bike should have been locked, I normally would have, but was unprepared and paid for it. I feel like a complete idiot, but also violated-the bike has been a huge factor in my sobriety and has given me a sense of accomplishment, hope and freedom that I wasn't sure would ever come back. My parents feel responsible as well which makes it a real gut punch
