In Conversation 1A, Michelle said:
Tá sé go deas bualadh leat, a Eoin.
It’s nice to meet you, Eoin.
If Eoin wanted to say the same thing in return, he would have had to use the emphatic form of leat. This is what he would have said:
Tá sé go deas bualadh leatsa freisin.
It’s nice to meet you as well.
