the most mature action

My principal asked me to stay until the 15th of Feb.
In fact, yesterday was my last day..and the main joke is, she told me stay until 15th yesterday.
My plans ruined. My gawd, principal like that very difficult to work larr...
Since she is my mother's friend and she went some meetings of SGM, then I really must sabar with her.
I really really sad to extend like this, informing me last minute. hate it.
I just sabar...and I think this is the most mature action of mine.
I grown up.. good good.
