Walk down the school halls and you'll hear the typical greetings - at least for our generation. "What's up?" "Hey!" Those are all normal greetings for our era, though surprisingly enough, they have changed how we view other greetings.
The other day, I replied to a text by saying "Hi" and was immediately bombarded with questions as to what was wrong. I was confused. Had I texted the wrong person? It was later that I realized that "Hi" isn't a typical conversation starter today. So why do we view 'Hi' in a negative light? Maybe it's because it no longer sounds upbeat and friendly. I googled the origin of the word and it was first said, in 1475, by a Native American from Kansas as a shorter term for 'Hey'.
Perhaps, it could be that, like always, the english language is shifting and "Hi" no longer sounds pleasant. Or maybe, it's just my friends and I.
