"Can you explain this gap in your resume?"

Yes. Life is about more than constant and meaningless toil for 40-50 years and a desolate twilight of failed ambitions. The social contract is broken and the system is a lie. You and I are both trapped in the same Sisyphean hell, where no amount working harder or longer will ever truly grant the rewards we were promised. The real question is, why are there no gaps in YOUR resume?
