It's All Gaelic To Me

Listening to Gaelic CDs tonight in our car, we were instructed to repeat after James:

James:  Hallo.  Is mise Seumas.  (Hello.  I'm James.)
Catriona:  Madainn mhath, a Sheumais.  (Good morning, James.)
                Is mise Catriona.  (I'm Catriona.)
James:  Ciamar a tha sibh, a Chatriona?  (How are you, Catriona?)
Catriona:  Tha gu math, tapadh leibh.  (Fine, thank you.)
                Ciamar a tha sibh fhein?  (How are you yourself?)
James:  Gle mhath, tapadh leigh.  (Very well, thanks.)
             Tha i snog an-diugh, nach eil?  (Davis says, "How is your snot doing?)
