Excuse me for my improper grammar and typos.
It's because English is my primary language, not my first language.

My first languages are C# and Java.
VB, ASP, JS, PHP and SQL are my second language.
Indonesian came as my third language.
My fourth language? I'm still creating it, I'll let you know when it's done!
