Umbrella is what we easily forget and leave behind in our daily life. When the weather is fine, we certainly don’t think of it; only when it's raining, we’ll carry it purposefully. But as soon as the rain stops, most likely we’ll forget  we’ve put it. It has to wait patiently and pitifully for owner to claim it, otherwise it’ll remain alone as a deserted umbrella.
Once I suddenly found my longtime (use) umbrella “disappeared” I really got lost and regretted quite some time my own carelessness.
Several days later, out of my (expect), I saw it quietly stand in a corner of the house where I worked. I was extremely glad to regain it. Looking carefully at it, though it was so familiar   me, I found for the first time its wooden handle （wear）out as a result of repeated rain-wash for years. I sought for it only when I needed it. It occurred to me that I should have paid(much) attention to it.
It sets me thinking. Around us there are always people giving us support in silence just like umbrella that protects us from the rain or any wretched weather. Will gou think of those individuals have helped you get through difficulty when you are leading a comfortable life?
