Let me tell you how my world changed

I had to leave my house for about a month after the Great East Japan Earthquake and Tsunami, as there was no gas. When I came back at the end of April, I saw a Japanese tit hurrying in and out of the birdhouse in my garden. I had set up the birdhouse somewhere around 2009. Birds had never nested in it before, and yet they laid eggs there while I was absent. Then the chicks hatched, and their parents got busy feeding them day and night. My heart beat violently when the young birds flew out of the birdhouse.
Since then birdwatching has become my hobby. My garden is rather small, but I can observe quite a few birds in it if I pay attention. I also notice birds and hear their voices whenever I go out on the university campus and in the city. I have become quite good at telling apart different species. Previously I was totally indifferent to birds - it is as if my entire world has changed.
As a matter of fact, we are aware only of the tiniest part of the universe that surrounds us. It is likely that if you open your heart to new sensations and experiences, you will find many more ways to enrich your lives.
