Sometimes they don't look like angels.
Sometimes they pretend they are not angels.
Most of the time, they don't remember they are angels.
I wrote a book about angels, published in 2009 in Japan.
According to this book, the easiest way to see an angel is "look in the mirror."
This angel came into my life a while ago.
While he is sleeping, he is doing his job.
Probably he doesn't know what a wonderful job he is doing.
