Met an strange incident on wednesday Night, 2 Sept 09

Wednesday night, i met an strange incident. I was being followed by one indian couple. Both aged between 35-40.

That night, my hubby fetched me back from my work. About 8pm we reached home. As usual, he took my LV handbag back and we walked separate ways. I went over to my mama's hse for dinner. Carrying my own handphone with me. Walked over to my mama's block. Pressing the lift, and wait for the lift to come down from 12th flr. While waiting, i noticed one indian couple was standing behind me. I heard both of them were talking to each other. When the lift was opened, i entered the lift first then they followed behind. And i pressed the button 7 flr, and i stepped back to let them press the button. At first, that indian lady wanted press the button but she was being stopped by that indian guy. I started to find something strange and weird on their reactions. In my mind, i told myself. I had to be very alert on their movements. When i was out from the lift, i intended to walk slowly to check which flr they were going. Never know tt they were following me out fm the lift. I felt even strange, causes staying at 7 flr were all chineses resident. They followed me to my neighbour unit ( 3rm) and i stopped there. Stared at them. That indian guy knee dwn for 10secs and when he standed up, his hands hold a 1litres water bottle. ( My Neighbour leave it outside to water her plants.) I started to ask them, what do they want and what are he trying to do. He replied to me by saying, " I am helping them to water their plants." After hearing that, My reaction was, HUH, with alot of question marks???? Then he continue to said. I knew them, I am their frenz. And i looked ard, noticed tt my neighbour's windows were all closed. I guess theres were no ones in. I started to worry, cause i am a pregnany woman ma. I need to shout for help. So i shouted for my mama, "OPEN THE DOOR." To alert the two indian couples, let them know that there were ppl at home. Then i hurry up entered the hse. My bros & dad were not at home. If not i could ask them to check on them, what r they up to. Told my mum abt the incident and immdiately called my hub to see over my blk on my neighbour unit. To check on the two indians. By the time my hub opened the window and looked over.. he couldnt see them. I guess they were gone. What's a cold sweat.
