I love you!
Somebody I had never met before helped me with a computer problem today, and I was so grateful, I yelled, "I love you!"
He was a man who spoke with a foreign accent. He looked at me a little bit strangely, but it only lasted for a moment.
I wondered if I was going overboard? Had I said the wrong thing? I am, after all, an American. We randomly scream "I love you," right?
About two hours later, I did something very mildly positive, and someone I hardly knew screamed at me,
"I love you!"
Suddenly, I no longer felt weird about the whole "I love you computer repair man" thing.
