Life lesson 1

I joined into work recently, i learned numerous lessons. Majority of workers in the place i work is opposite sex. I realised that, the place like this got a lot of gossips and sophisticated relationship. One of my colleagues attracted my attention as she possess charming voice and moderate attitude.
She always has eyes contact with me and quite close to me. I have to say, i dont have any intention to initial a relationship with her. I thought i was mature enough but somehow i still that naive, keep expecting someone else. I always give my hands when they need and also when she need. That day, all of them play the fool and left all the works behind. They just sit around there and scrolling the screen of d smartphone while im finishing all the works. To be honest, i didnt expect anyone of them will aid me but i thought at least she will do smth for me like asking others to help me or ask me whether i need a hand or not, but for sure, i definitely will reply "no thanks, im fine". I felt a bit disappointed that day and i tried to figure out whats going on, is it im acting a wrong characteristic or i supposed to finish my own part and act like them left the rest behind. 
I realised that i have responsibility in this matter as i expected smone to do smth for me. I know human is selfish and we always prior our own profit under corresponding circumstance and situation, i know this truth long ago, but i failed to operate it 100% in my daily life. At the meantime, i found no wrong about my characteristic, all of the features im showing not for others just because i wanna to do so, i want and willing to take the my obligations. 
In a nutshell, i insist to show the same characteristic which i consider is right and the less you care about others, the less hurt you will obtain.
