She won't admit it, but I'm hearing from all these helping hands that she showed up late to interviews, didn't send her resume when requested and even failed a drug test. Now she has come to me for help, and I told her I'd let her know. The truth is that I'd prefer not to put my name on the line for someone who is apparently irresponsible. How can I be honest with my friend about these missteps that she never even told me about?
