Questions About Malaysian Girls Looking For Men

How come there are a lot of Indians in Singapore.?

I went to Singapore for 4 months and it was absolutely flooded with Indian people. I expected Singapore to have Indonesians, Thai’s, Malaysians and Chinese but why are there so many Indians there.
The trains and buses had 95% of Indians and 5% of southeast Asians.
And i went on a bus to go to this local shopping center and 3 Indian boys wouldn’t stop starring, 1 Indian man looked like he was having an orgasm and a group of older Teenage Indian boys were perving at this 10-13 year old young Malaysian girl wearing a skirt which made 1 of those teenage boys to lie down slightly and try to look at her ****** If i wasn’t sitting next to the young girl then those group of boys wouldn’t think i was her older sister and they probably would have ended up kidnapping her :-S On the streets in the city, there were dozens of Indian people sitting on sidewalks, gutters of roads and some also had to squish up on benches. It was crazy.
So why are there a lot of Indian people in Singapore????????????
