Re: asking certain questions
kayz, you never know man, there are ppl i know that come from very good family back grounds but their sons and daughters is involved in very sort of wrong activity while their parents are unaware of it.
my first suggestion to you soconfused is that get someone on your side from your family brother or sister, could be your best friend too. ask them to observe, which later on you can sit down and find out that the two of you observed was the same or not. what you have to observe is the behaviour. and get a vibe. you can ask for clarifications later. then ask your parents what do they think. try to gather as much data without asking too personal questions and then decide do you need to meet again or not.
also someone must have done a background check from your side. so you must know where is he from, where he grew up, what he studied, where is he working, what university did he go to etc.
