During the certificate awarding , his classroom teacher asked about his presentation , and he said he didn't understand . She didn't believe that . Considering he knew to show up to the group meetings when he felt like it , and was there when we discussed and practiced yesterday ... no one really does . But oh well . His professor from Temple will deal with that . 
Question: Why did the guy show up to group meetings when he felt like it ?
Because he is irresponsible .
