To be an adult is to be able to enjoy a time by myself. (I don't think this expression is right English..;;)I guess...

When people are young,they tend to do things with someone no by themselves.
As we get older,we become more independent.

Can you travel by yourself?
Can you go to watch a movie by yourself?

my answer is "Yes" What about you?
Of course it's fun to hang out with friends,but I also like going out by myself.
I offten go shopping or go to caffee alone.

I think this is how I think 'To be anadult'.

hmm...I am not adult ENOUGH,but I believe I'm taking the stair to an adult!lol
At least...I don't need 3 alarms to wake up every morning!!;D
