Then come the two words that we hate to hear the most from people.
When we hear this, it is always some an old friend, an ex, or some hook up that we can't seem to shake. Whatever the case, we can see through this very thinly veiled attempt to brush away the awkwardness that has ensued since our last communique.
Calling us "stranger" isn't particularly funny, but it can be filed under those little catch phrases that people use in case of emergency situations where humor is escaping them but to not be funny would be even worse than the unbearable silence that would otherwise result in this chance encounter. For example, when you explain a scenario to someone and they don't know how to comment or console you, they will say "Well, you'll have that."
What does that mean? It makes us cringe.
"Hey, stranger" is ironic because we'd most likely enjoy it if you were a stranger to us, or otherwise we'd be txt'ing you non-stop like those in our Top Friends on myspace.
If you're going to bug us, at least have a snappy opener.
