A friend of mine and I chatted on YM and she shared to me the horrible experience they had in their dormitory. According to her, their building was intruded by a burglar and one of her dorm mate's room was robbed, taking her DVD player and her laptop. CCTV had recorded the actual intrusion of that burglar and it even stayed an hour in that room. Now, the whole occupants of the dormitory feared that it might happen again.
I was thinking, if this happened to our home, good thing if the burglar only robbed some stuffs. But what if it's more than that? It could be possible he'll leave the house on fire so as not to leave some traces of his identity. It then occurred in my mind that an alarm system and a home insurance is really a must.
