Im reading a manga called Yotsubato and this phrase occurs when Yotsuba dad is talking to a girl witch is his neighbour.
He says: 変な奴だって思う子がいたら.
The meaning is: If you see a girl that makes you think... "It's a weirdo!"
So, my question is, why the use of "makes you think", is it only because he is talking to this girl in particular or because of the "って" or something ? Im really confused with this phrase.
