If a persons is important to me .. i.e. someone really specially .. then she can ASK anything .. .. .. .. I am not that kind a person who puts unreasonable don’ts and do’s .. .. .. but if someone is random .. .. or even just a friend .. then .. I feel very annoyed if something comes to my personal life .. and specially investigation
if it is rishta thingy, then i guess @NaMaan answer is better .. ..
