I love small children (Not to be taken out of context)
If the child actually likes you, he or she will honestly show it. I think there's nothing greater in the world than being loved by a child. That really means that you are a good person, and in her world always will be.
And many of the things you do together seem trivial, like watching a movie together or letting her paint on a huge piece of paper and letting her show it to you all happy and stuff :3 But it all counts in the end. Make her favorite dish to eat, keep her entertained
I sometimes fear that I won't get a child, because a child is literally the thing I want most in the world. Not now, but later. But actually not in a so-far future...
