wasteing time

OMG- it was 18:36 on that frieday afternoon and I was still standing alone on the principal square in the citycenter. We were supposed to meet there at six but noone showed off.
After another few minuts of waiting my classmates finally arrived. "Well Portugal"- I thought and went with them to the home of F. .F. lifes in the by far smallest apartment I´ve ever seen.So atfer arranging 4 chairs arround a tiny table we were ready to start. But what was supposed to be a groupwork for school turned out to be nothing more than a siteseeing tour through Lisbon with the help of google. So after 3,5h of doing nothing the Portugese decided that the best we could do was to send what we have to our prof and wait for her to tell us what to do.
Great, 4h of wasted time...
