Your lies would be effective if you were the only source of the truth.
However, your parents (for example) may tell the truth to their friends, who pass it along to their friends, who also share it with their friends . . . and so forth, until everybody who knows you knows the truth and also knows you to be a liar.
Or maybe your alleged employers have openly denied ever having you on their payroll.
Or maybe your alleged coworkers have openly stated they have never seen you on the job.
Or maybe there are simply no night-shift jobs for which you would qualify in your area.
Lies are always found out, one way or another. Obvious lies, even more so.
