While talking to my 2 year old grandson the other day I said, "you know your my grandson...!" He replied, "no I'm not...!" I said, "no really, I'm your grandfather which makes you my grandson." Again he replied, "no your not." Look, I'm telling you the truth...! Do you know the difference between telling the truth and telling a lie....? He replied, "no." Ok, look out of the window. You can see that the sun is out, the sky's blue, birds are singing. So if I said, "It's daytime, you can look out the window and see that I'm telling you the truth because you can see for yourself that it is truely daytime. But if I said, "Look out side, it's night time, and you look out the window and see a bright sunny day, do you know what that would mean...

??" He replied, "YES..., it means I'm your GRANDSON...!!! Oh, god...
