I am determined to have my darling learn the Teochew and Hokkien languages by having my parents-in-law converse with her in them.
However, it would not happen if I myself continue conversing in Mandarin with my in-laws.
While my parents-in-law switch between Teochew and Mandarin with ease, I really grew up learning and speaking Mandarin, all while Teochew and Hainanese were spoken all around me among my elders.
