Ignorance is a bliss --- is it ?

If you are thinking that this post involves some philosophy regarding the title, then you are at the wrong place. The title "Ignorance is a bliss" may have been the target of several discussion groups, but here it is stated in context to something. That thing goes here:
"It is common practice to see boys roaming around with girl friends. But what happens when one of the friends of the boy is in close proximity to the couple. What does the boy do ? Ignore you or introduce you to his girl friend."
Most of the times i have noticed that the boy chooses the first option. Quite uncanny huh !
There are umpteen number of times i have come across situations where i happened to see one of my friends ( or take seniors) along with their girl friends and they simply ignore even after making eye contact. Its very similar to a party situation where you go & say hello to someone & that someone is not at all looking at you & just walks away & you become the joker.
Is it that the boy is so timid that he is actually worried of his girl friend being purloined by his very own friend ( Believe me that does happen sometimes). Or something else...
If any of such guys is reading this post he may have the best answer to this. For some people "Ignorance is a Bliss".

Its alright when the boy has not noticed you and you are constantly looking at him waiting for him to say "Hi" first. In that case the boy's friend is so cunning that he was actually waiting for such a situation to take place & then he can say that his friend was ignoring him. In such cases the boy, his being zero fault, is the victim again.
