A distance of 500 miles separates my college from my hometown, an old city, where my parents have been living, but my heart has never been away for a single step, because the lesson from them will be a gift of lifetime.
When I was still 15, the laid-offs, or rather untimely retirements, of both my Mum and dad, arrived by far earlier than ever expected. Moreover, it could be hardly imagined how much their careers meant to them other than earning money.
Nevertheless, it would be not long before they managed to get over such a blow. They thus underwent all kinds of odd jobs they could run into, be they dirty or painstaking. That way with sufficient money for my tuition fee and living expenses I went through my three academic years.
Now one of them is getting weaker and both older, but the lesson that God only helps those who help themselves they taught me will endure in my mind despite the passage of time.
