Kids get smart quickly....lol.

I had a boss when I was quite young and green who played a game with all of the junior managers, it went like this. If you walked into his office and said you wanted to ask him a question he would stop you right there and ask you if you had a dollar bill (this was a while ago when a dollar would actually buy you something). You would of course say yes and then he would ask to see it, so you'd pull a dollar out of your pocket and he would say something along the lines of 'Yes, that's a dollar, just set it on my desk in front of me'. Then he would lay out the rules:
If your question was not very bright and if you could have come up with the answer by using your head for more than a hat rack - he kept your dollar but would answer your question.
If your question was a good question but you had asked him this question before and had just been too lazy to bother to remember the answer he had already given you - he kept the dollar and reminded you of his previous answer.
If your question was a good question and his superior experience and knowledge were now called into play, experience and knowledge that he had paid dearly for over the course of his career - the he would give you the answer and you kept your dollar.
Knowledge is not free, it is hard earned and should be valued as such.

They are always testing..... Flashback, good times

If he's anything like mine? Yes, he's totally trolling you.
