My husband and I went to a New Years Eve party one year. We knew the street number but not the house number. We pulled up to a house with a large number of cars outside and thought this must be it! We ventured in, greeted the host and the hostess, gave them our dish that we brought and proceeded to sit down in the living room. Noticed some odd looks...We looked around.... looked at each other... whispered "do you know anyone here?". Asked if this was so and so's house and was told they live 2 houses down! We all had a good laugh and they gave us our dish back and out we went. Very embarrassing.
