shut up if you don't know

sometimes it is better to shut your mouth when you don't know and it is good if you can share your knowledge and try to correct it if you have given wrong info.

this morning, one girl ask me which is which and since that is my area, so i tried to give her the answer and correct it when i found out that the answer was wrong. suddenly, there come one drosophila sound "eyeetttttttttttttt yeet yeet"(what sound is that? hehe..) stating that don't asked me Malay, i only know English. hmm...how??
