Right now I am very angry with B.M.’s laziness: even after I gave him all the response letters, he cannot spend due effort to draft a proper letter for DE. Besides those flashy flattering (which will surely turn off the DE), he simply copied the introduction of the paper. Come on, if you have this attitude, no more collaboration in the future.
I have to do it myself. After all, this is my paper. Stick to my version.
