I am surprised people think this is odd or suspicious. But then again, I don't know anything. I think after meeting them in person, it is not strange to send a Facebook invite, right? Or to have each other's phone number? I agree it is a bit odd that they immediately contact you after they know about your existence. But why does it have to be negative?

Overall, the negative view of men is also shocking to me. Not saying it is correct. I am naive after all. It is just unnerving to see people warn others about men who haven't done anything but send a message, as I am a male and females may have all kinds of reservations about me because I am male too.
