How David Bowie sings it, " I don't believe in modern love" because basically humans suck these days cause society has molded them to not know what true love is
Same principle as the Involuntary "You Too", this is when out of habit you say I love you as you hang up the phone. This causes great embarrassment, but it happens to everyone sometimes.
Perfect example of the Involuntary "I Love You"
Boss: Ok well good work Cindy. I'll see you at the meeting this afternoon.
Cindy: Ok Mr. Smith. Love you, bye.
