This really sounds like it could have been so much worse.  Of course it is really sad for the people who lost their homes and the person in the hospital, but everyone made it out alive which is a miracle.  Oftentimes in fires people do not make it, so I would say it is a blessing that they all have their lives.  They will have to rebuild which will be stressful but at least they have each other and are alive.  I think it is very fortunate that it turned out this way.  I would say these people are lucky.
