Übersetzung - Niederländisch-Englisch - - wat bij elkaar hoort, zal bij elkaar komen.

What is that supposed to mean?

What looks the same/matches (resembles), will come together (assemble)? Hmmm, maybe I shouldn't have used "assemble", but it sounds nice that way :P

Don't they use that proverb when talking about which sorts of people fall in love with eachother?

The saying I can remember is "Birds of a feather flock together" meaning that similar people spend time together. Does that convey?

I'm not sure we're talking about people here, then again, birds of a feather aren't people either

Oh, found something on Wiktionary
Haha, take a look at the French equivalent!

Oh...you had done the translation into French then!

Dag Dennis i voted wrong , i hope you dont mind
to me the english means people who are SIMILAR tend to get along, come together.
the dutch is more about destiny, saying people/things who/which are MEANT to be together, eventually will
