Danger in the Park

I was jogging in a park in Jurong on Monday, when I heard a hissing sound, and spotted a black snake disappearing into a drainage hole...it was such a shock for me! I had never expected a snake in a neighbourhood park!
I suspected the snake was responsible for the absence of the rats in that park too...Prior to the incident, I had always come across many rats scurrying in the park, and always had to stay vigilant so that I woulnt step on them with my clumsy feet...
The snake terrified me so much that I could feel goosebumps on my skin, when I jogged, and instead of jogging, I ended up running away for my life...
The next day, I reported the incident to Jurong Town Council, which was responsible for that area. They despatched their pest control contractor to attempt to locate that black menace. But after two operations, they still failed to locate it. Now, would they think I'm pulling their legs?
Was I too stressed to the extent that I saw a mirage? Or was the contractor doing its work? Or did the Town Council get the right park?
Think I gotta find some other place to jog, else instead of destressing myself, I'll be stressing myself even more with the constant thought of the snake in my mind...
And one more thing...Ah Teng, watch where you run the next time...Pls wear your contacts!
