my MOUTH vs my MIND

yesterday i went to alor star mall
don't know want to do what
when i was walking,
i saw krishnan da donkey (almost the same name with my moral lecturer) also in alor star mall.
the difference is da donkey is lecturer in uta and he teach math and i attended his class once. (i forgot why i go to his class, so don ask me after this)

my mouth : omg, why he is here?
my mind : mati liao, why he is here?

then, da donkey(dd) come to me and said: hai
my mouth : hai
my mind : stupid donkey, why you didn't say hai to other people but me.

dd : do you think i am handsome
my mouth: hmm...yes.
my mind : jiak sai la u handsome. face like this also call handsome. XXX(sensored)

dd : do you think my lecture very interesting?
my mouth : not bad.
my mind : walao, you beh paise one hor? half of the class are sleeping while the other half go to toilet. this kind of lecture also count as not bad?!

dd : if you are my student, what will you say/do to me in the last lecture?
my mouth : of course i will take a photo with you.
my mind : of course, take your photo and put as my dart's target

dd: mj die ald, you know? his song is so nice
my mouth: ya. very sad
my mind : ya, very sad. why you are not the one who die

dd: time is late now, gtg, bb
my mouth : bb, take care
my mind : must be take care la, so many students want to kill u.

this is just an example to show what my mind and my mouth are doing
there is nothing to do with anyone inside this conversation.
