14. I believe it is Very Important for parents to address a child 's every query. Cause you should remember some very important things :
             (i). Children are in a very impressionable age . They tend to take things without knowing if its right or wrong cause they have not yet formed their own concept of what's right, what's not.
             (ii). Children are very curious. If you won't tell them the answer, they'll find someone who will .
             (iii). If you negate them for their first question, then they may keep you as their last priority for getting their answers. They may first go to those people who had helped them the last time . And so, this may lead to 'diminishing of their trust' on you .
             So, try to answer all their questions. Of course, there are things which can't be told to them before age, but then too, you should treat the information as knowledge & try to tell the answer in such a way that you eliminate the uncomfortable part & give them the information which would satisfy their quest.
             Do remember that it's much better to handle these queries by yourself then to let them seek the answers from others. You may never know if they are being lured into the dark/dirty side of human existance. When you handle their queries & satisfy them, you can be rest assured that they are less likly to ask the same thing to someone else. And , as n when , they gather more knowledge, they'll be able to form their own notions of right n wrong & thus become more cautious/careful . And ofcourse, their trust on you will also multiply & your relationship with them, will also become more strong. 

        10a. It is difficult, but not impossible; to eliminate Ego in a relationship. The simplest way to do is to consider yourself as a Student who's ready to learn from everyone & from every situation . It is difficult if you try to find your respect in other's. But it becomes quite easy if you respect yourself & are not dependent on other's for it.
