Tainted Love
First date I ever went on was when I got my first kiss. After we smooched I looked at her and said “… I love you”.
After that we just stood there for 30 seconds and then I just said good night and left in the most awkward way possible.
The next day I explained that my response was a “heat of the moment” kind of deal; and things were fine after that. I was 15 at the time. I still look back on it and think to myself what the hell were you thinking?!
