Mo chreach! Eil cuimhne agad gu bheil mi a' faicinn an fhiaclair aig ceithir?
Heavens! Do you remember that I'm seeing the dentist at four?

Mas math mo chuimhne nach ann a-màireach a bhios tu a' faicinn an fhiaclair agad? If my memory serves, it's tomorrow that you're seeing your dentist?
Mas math mo chuimhne nach ann an-dè a bha thu a' dol a dh'fhaicinn an fhiaclair agad? If my memory serves, isn’t it yesterday that you were going to see your dentist?
Mas math mo chuimhne nach ann aig trì a bhios tu a' faicinn an fhiaclair agad? If my memory serves, isn’t it at three that you're seeing your dentist?
