I have four elder sisters and whenever I bring a girl home they ask her to many questions and don't trust her. How to stop this ordeal?

The answer is simple: don't bring her home.  Leave that for the one and only, the one you intend to make a permanent connection with, and then, limit your time there, be present yourelf, make sure everyone has something else to do other than to sit around and perform an inquisition. Problem solved.

dont bring her home and see her somewhere else

Stop bringing any girls home. Talk to your mother also about the bitc h's.

My sister used to get annoyed.  The thing is though...i’m always right.  I always can get an easy read on her suiters.  And i don’t even ask questions it’s just conversation.

Don't bring girls home. Go sit in the park if you have to. You'll never get a girlfriend with 4 idiot sisters!  Good luck.

you need to tell them to back off, and stop bringing stray girls home with you
