Can You Let Your Bestfriend Date You Brother/sister?

question: can u let ur best friend date ur sista?
Answer: NO NO NO NO NO NO NO and NO NO NO NO NO!!!!!!!!!!!!!!!!!!!!!!!!!!!
Reason: have firsthand xperience in this type of thing, allowed my friend to date my sister, the result is my friend and i no longer see eye to eye, and my sister dosnt talk to me anymore. ironically, the two of them are now sworn enemies, but they still aren'n talking to me. i was used as a sacrificial lamb for settling their quarrel once. when there was no me to sacrifice again, they dumped themselves. i still have not completely forgiven them for what they did.
My Advice: don't EVER ALLOW IT. IF IT IS ALREADY HAPPENING AROUND YOU, NEVER, NEVER NEVER HAVE ANYTHING TO DO WITH IT. MY brother, IT WILL NEVER END WELL.

Only if they are both ready to get married next day. 

i think its better to stay away from that territory

there is nothing wrong with it, but many wrong things could result from it

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

for where

never
