In fluster for nothing

Why in a fluster, everything in control...this colleague of mine so not in working mode, worry for nothing...she will always in fluster that things is not going in tune. Well, i have taken care of the details and informed another colleague on this. This colleagues never pay attention to details and asking silly questions. Come on, wake up wake up, not time to sleep, but time to pay attention and do things accordingly. She will forget about this and repeat the same old mistake, fail to learn from experience. When things happen, she will excuse herself from office and let us take the burden. Such colleague we have. Just our luck
