Yes,idioms,manner of speech,and lexicons,trip up someone not born in the US,slang is another tripping point I look for when a Woman contacts me showing interest.

Be suspicious,do a reverse phone number look up,I used one last night that told me a lot about the Woman who showed interest in me. it was www.whocallsme.com Many phone calls are re-routed to Nigeria or any country other than the US. About the safest is a local contact,not someone hundreds of miles,or further away(although,romances have been created here, and a few marriages have been taken place).

How about when they try to get your phone number right away. What are they trying to achieve?

I have had about three recently whose messages lead me to believe that English is not their mother tongue. Start asking questions. It's not difficult to catch them in a lie.

The two Women I met on this site seemed genuine,but when tried a phone call,it was re-routed to Africa,when asking my ISP,they could only trace so far,the call was full of distortions,and a noisy back ground with African Men talking,so beware,do not give up your heart without verifying just who are where youare talking to, "Catfishing" it's called.

Just like any other offer; if it sounds too good to be true, it probably is. That said, I know several people who met the love of their lives online. So, to a certain extent, like everything else in life, some people are luckier than others.

If they show interest, in my experience, they're fake! lol

Let's hear some stories!
