Children are sweet ,innocent and wonderful. We fall in love with them even before they are born and the love just keeps growing as we watch them grow. Even if they disagree with what we say, we always feel it's okay.. they r just kids , after all !
With Pets, we have total control over them and they never disagree or argue with us anyway.. so, yeah, we love them as well !
With adults, we have ego clashes, we want people to listen to us and if they don't we feel hurt. We expect everyone to give us as much importance as we give them. Any small issue can be easily blown out of proportion and we rarely try to see it from other person's point of view. But then, it may not be true of our relationship with all adults, at least not from our immediate family. I mean, I love my husband as much as I love my child !
