Sorry is sorry in dutch, so we use it in english as we do in dutch.
- Regretting (I'm sorry I hurt you)
- Excusing (I'm sorry this happenend (when it's uncontrollable)
- Politeness, adressing (sorry, can I pass) wich would be pardon me in correct english. But We Flemmish use all 3 (sorry, pardon me, excuse me: "sorry, pardon, excuseer")
