Input:  Person1:       Did you meet the new girl in our sales department . She is taking the place of Maggie during her alternative leave . 
 Person2:Did they finally fill that post , how come I haven't seen her ? She must have not been inducted yet . 
 Person1:        I guess not , They haven't officially introduced her to the whole staff yet , she barely started yesterday . 
 Person2:Is she just working temporarily ? What are they going to do when Maggie comes back from leave . 
 Person1:        If the new girl is competent , maybe they will promote her when that time comes .
