I think when I have to take care of my pet. :)

When I have to take care my little sister's daughter and nephew,I feel like an adult.

And now I will graduate,I have to find a job and have my life.I have to be an adult. 

Knowing the fact that I have crossed 18 makes me feel like an adult

Well I didn't mean to write like that, even I cannot write in that way, neither do I want to learn. I was only referring to some words, you know Gosh, Yikes, Yup/Yep and so on. But I really appreciate your kind advice. Thanks ;)

For me it's: responsibility at work, patience in life problems and caring for parents and younger.... but don't forget, everybody of us is a child in soul....<img title="Wink" src="http://www.italki.com/Scripts/tinymce/jscripts/tiny_mce/plugins/emotions/img/smiley-wink.gif" alt="Wink" border="0" />
