This similarity is only because they are close each other geographically.
I should also admit that Sinhalese people and Indian Tamils are in same family with Indians.
I believe you are going to meet with Buddhists generally cause there are 75 percent Buddhists in Sri Lanka.
You can meet Sinhalese, Indian, Tamil, Moor, Burgher girls while you are searching them. Firstly you should find a city list of Sri Lanka and add at the least 20 city names to Omegle interests.
They always say "Miss you", "love you", "mahal" , "I love you so much", I know this is all pretty obvious that they don't love you still any guy that believes they do is going to end up terribly hurt and broke.

There are also Malays, Kaffirs, Burghers, Moors, Veddas and Tamils. They know Sinhala and Tamil Languages but they are still good at English.
I don’t think that you may chat with a Vedda on Omegle but you can find another of these girls. I believe you will have chance to find these girls online.
