Bad questions !!!

Here's something to twist your brain around, just in time for Christmas, too! Christmas Tree There were 4 angels on a Christmas tree (besides other frou-frou). Two had a blue aureole and two yellow, however none of them can see behind his head. Angel A is on the highest place and he can see angels B and C, which hang below him. Below hangs angel B, who can see only angel C under him. Angel C can't see anybody, because angel D hangs under a twig (nobody can see him and he can not see anyone either). Which one of them will be the first to guess what his own aureole is?

Yes, it is hard to get involved when there are 100 posts asking how old you are and what browser you are using. It takes time to sift through the topics and see something worth replying too. Been trying to start topics that require discussion. Like things about road rage, quitting smoking (a lot of threads about that topic too, btw), who works online, etc. Been doing my best to give thought to repsonses to those who reply as well. This is a forum, right? Seems to me there are lots of polls in here, like you said, they require and answer of "yes" or "no" which I do believe is against the rules anyway. Bet this place keeps the moderators busy as all get out.
