My youngest son doesn’t talk much. He has severe autism (自闭症) that limits his ability to  1  and communicate. And it also  2  him in his own world much of the time.

3 , when he laughs and smiles he can light up the  4  day. Sometimes he will break into sudden giggles (咯咯笑) for no apparent reason at all. When this  5  my daughter and I will often joke that his dear grandma who had  6  and her angel friends must be tickling (胳肢) him from heaven.

The other night  7  I was busy working at my desk, I once more  8  his musical laughter behind me. I asked, “Son, are the angels tickling you  9  ?” and got an even louder burst of giggles as a(n) 10 . I smiled and turned around to  11  him. I found there he stood  12  the ceiling fan with its glass globe light above his  13  like a halo (光环). Hanging from it was a glass angel that we had  14  to the light rope years before. Both the angel and my son seemed to sparkle（闪耀）in the  15  before my eyes. It was then that I realized that my daughter and I had been  16  all along. Angels are watching over my angel. I was sure too that they were sharing in every bit of laughter and  17  that they were blessing this world with.

The word angel originally  18  “messenger”. That is what my son is to me and to everyone he meets. He is an angel whose  19  are ones of unconditional love and unlimited joy. He may not say many words but his soul speaks volumes. May the laughter of angels  20  bless your life as well.
