Some people just have to ask hard questions only when speaking over phone. Even when you are in traffic or shopping. How good are you then to give them a fully analyzed reasonable making-sense answer?
Sulit diungkapkan dengan akal pikiran ditelpon – It’s difficult to express reasonable thoughts on phone [to reveal thoughts with making sense]
Tapi tadi kamu bilang kamu cinta aku – But you just said you love me [actually: said before]
Apakah itu masuk akal? – Does it make sense (then)?
Akal – reason
Ungkap – said [formal]
