I feel Dumb
No need to feel dumb - we've all done something like this and missed the obvious.
The worse example I can think of was back in the '70s when I lady at my work bought a brand new Monte Carlo. Drove it off the lot and it died on her on the way home. Had it towed back to the dealership where the mechanics worked on it for 4 days before they finally called and told her it was out of gas.
Imagine how they felt!
