My dear undergrads,

you. don't worry about the molecular analysis. it's MY problem. not yours.

you. focus on your project. why do you like to ask irrelevant questions?! wait. don't answer that. i forgot that i don't wanna know.

and two of you. i clearly stated in sms and emails (note that it is in plural) to increase the sample weight to 2 grams. NOT 0.2 grams. please don't make me repeat myself again. i might have to hurt both of you.

finally, don't run off and complain about your woes to the boss. boss will find me and complain about you to me. i do not need his help to destroy whatever patience i have left for all of you.

Sincerely,

Me.
