I understand a little... I don't know what ''heureux'' means, but I think that you said that you are ''heureux'' of corresponding with a brasilian... is that right?
''Hun'' means ''honey''. Is literally a sweet way I like to call some people ^^
And ''^^'' is like eyes. When you smile your eyes become that shape ''^^''... well, maybe...
I hope you understand it now ^^
So, about SKYPE (I don't know if you noticed it, but I'm the same girl from notes... I think you did XD), is that free charge? o.O
Hugs!
