Why do my friends lie to me about this? **Help Me Outt** thnx:)?

well i guess i can say that im a drop outt, i droped all my cles but im going back to school in september, and all my friends just graduated last month and they said that they needed no more cles, and that they were happy that they graduated and leavin in the fall for university. but another friend told me that they werent gonna be leavin town soon cuz they still need to go to school here they need to upgrade sum of the cles they took and i was wonderin why they didnt tell me this yet? i wonder why they keep lying to me sayin that theyll be gone for the fall?
