"I once found a guy I was dating dirty-texting another woman and I completely lost my s**t. Texting is so dangerous! I won't even give guys my number, because I know me. We'll start texting and he'll start emoticon-ing and I'll start emoticon-ing, and soon we have a big mess. I'm a very flirty person in general."
