21 and becoming of age

Turning 21 really hit me by now. Turning into a full adult really has emerged different problems I face in life!! I am really trying to cope with it. Even suddenly taking adorable stares at a toddler in the park is freaking me out. I used to dislike toddlers and don't even bother turning my head for a second look at them. Now im like 'eeee she's doing this n that' and I find them so cute. I really didnt like babies previously...until recently.
Even today I was sitting in the passenger van with a couple of friends as we were heading out for some activity. At the end of the ride i realised, gosh, I have become slightly (i think or maybe more) motherly -as in kind of reprimanding the opposite genders that they're either playful or noisy.
Well one instance was that one guy was playing with the safety belt hooks and it was producing some noise and he just kept doing it for a few more times. I chided in and told him 'eh your hand itchy is it..' WHAHAa i dont know about you reading this but for me to say such a thing is as if I'm mothering the situation.
In a second instance, was when this other guy was like talking or shouting something loudly that it made me say oii dont shout so loudly or something of that sort. In this case I was trying to protect in one way or another my girlfriend who got really terrified because someone shouted very loudly at her the night before when she least expected it. So yeah, to think that I even bothered about ticking these guys off to me made me feel that I was being more motherly. Perhaps not for you reading this though. It is just making me go arrrh... i m growing up.
