learn to speak Samoan

I’m half half Samoan, half Swedish – Irish mix. I’m 29 and married to a full blooded Samoan…or so he says…fresh off the boat. I don’t speak the language and can’t communicate with even my own grandma. WE are going back to the islands in September to meet my in-laws and so they can meet their grand-daughter who doesn’t speak any Samoan either. I want to be able to talk to them and understand them (specially if they are talking about me ya’ll know what i mean!)
