Apparently the iPhone has the ability to not only "reply all" in e-mails, but also in text messages.
I received the following picture text from Lauren:
Without thinking, I replied, "in love" because I am in love...with Nantucket (as pictured).
What I failed to realize is that she had sent this picture to multiple people. I realized this after I got three new texts from numbers I didn't recognize - asking me "who I was in love with" and asking "who is this?"
SO lesson learned: for all you iPhone owners out there - don't reply all to a group text if you don't know all the recipients.
It causes a lot of confusion!
