Good Work!

"happy time" should be "happy times", "got me out of difficulties" might sound better with a many, or descrptive word in front of difficulties, it works how it is, but that just might make it flow better.  "lighted" should be "lit", "that make" should be "that makes"

very poetic. lucky guy! lol
