He basically was asking you to lie to him wasn't he? Come up with some time you can justify in your own head and it leaves his hands clean doesn't it?
I had the PO ask me to lie, indirectly. He said he wouldn't be able to help me unless I was active. He said I know you study with your daughter. And he looked away from my eyes when he said that. I was new to the hall so he know if I studied with my daughter or not. So I just turned in a fake time slip. I have never studied with my daughter.
