hermano, por favor, no me da un dolor

Dear Colleague,

Thank you for your email earlier today inquiring about whether Action C had been completed.  Short answer:  no. 

Longer answer:  No, because Steps A and B, which are required in order for C to occur, have not been performed by the person responsible for those tasks.  That would be you, by the way.  Three months ago, you asked me how to get to C, and I gave you detailed instructions, including a freaking template.  Nothing about the process has changed in the intervening months.  You still need to do A and B to get to C.  Asking me about it again isn't going to get it done, nor is it going to prompt me to volunteer to take care of it for you. 

No love,
moi
