What am I to do?

Title: What am I to do?

I thought that by deactivating my Facebook account, he would stop stalking me. But I was wrong. I was oh so wrong. He's still out there somewhere, watching my every move. Ya Allah, I am so afraid that I am close to tears as I am typing this entry out. Just last Friday, he was at Assyakirin again. This time, he wasn't alone; he was accompanied with a group of friends. I caught him stealing a glance at me through the door of my class, and his friends did the same. They gave me a smile. The kind of smile, that'll just creep the choo-choo train outta any girls, alive. Let's give this stalker a name. Let's call him Z.

Their KBR class, was just at the opposite of my Pergas class. They ended half an hour earlier than us. But Z, and his group of friends, were amongst the last few batch of students to leave their class. They only left their class at about 15 minutes later, together with their Ustaz. Through the corner of my eyes, and from where I was seated at, I caught them taking a peek into my classroom again. I recognised the Ustaz who was teaching them; he's my father's colleague. I shall not reveal the name of the Ustaz here though, so I shall leave his name anonymous. The Ustaz is a young chap and Z seems to rather be on a close term with the Ustaz.

So when I got home, I reported about the matter to my dad. I mean, how could the stalker and his group of friends, still have the audacity to smile / steal glances at me? As a girl, I feel insulted by that. I really do. Then on Saturday, my dad discussed about the matter with the above mentioned Ustaz while they were at work, and the Ustaz was surprised to hear about that.

All these whole while, the Ustaz knew that Z was particularly interested with this Pergas girl, but the Ustaz didn't know who it was; until yesterday. Ustaz didn't know that Z had his eyes on the daughter of his own colleague. Ustaz was surprised to learn that the Pergas girl, that Z had been talking to him about this whole while, was actually me. My dad told the Ustaz about how Z wanted to reserve me for marriage and all that. Of course this sorta angered the Ustaz and he told my dad that he would confront Z, about this matter soon. 

& that leaves me worried. I'm half thankful and half afraid at the same time. Because what if Z attacks me back? I don't know what to expect, except to pray to Allah, to protect me from the evildoings of mankind...
