I helped a student financially and that guy has got through OLs.

I know OLs is not a big deal. But this guy was about to give up education due to financial issues.

P.S. : I can't stop him calling me 'sir' because I got to know him from a friend who is working as a teacher in his school. He's calling him as 'sir' since my friend is his teacher. And calling me from the same.
