Her attitude. Usually you can see it in the way she carries herself, like even the way she walks.

How's everybody.
I'm single.

I meant 'these' sites, rather than just "this" site, in particular.

I don't like this site because they only let you send 10 messages per day. They also tried to trick me into giving them my phone number to complete my profile.
Additionally, most of the people that use this site aren't who they claim to be; meaning the person in their picture is not the person you are typing with. So, don't feel bad if you're "rejected". If you don't see them in a webcam, interfacing with you in an actual conversation it's likely they are not who they claim to be anyway, and are most likely here just to bring people down.
I've cancelled most of my online profiles, and I'll likely do the same here. Maybe you'd meet someone at school; if you're not going, maybe you should check it out.
