1st Day back home in VA

Attempted to contacted the roofing company that did my sealant on my roof.  Could not get an answer nor leave a message the mail box was full.  Tried calling several times.  I did get my hearing aids back to working that was to highlight of my day. 
Last for the first time I decided to kick back, "let my hair down" and party with Kayla.  Just as I was enjoying the moment dad starts his repeated calling thing to me for the night.  Kayla was talking to him and all of a sudden he quits talking.  All we could hear was Isis barking in the back ground.  We Kept shouting to him "nothing".  Here it was we did not know what happen to him.  We tried for 15 minutes calling him back, with it going to voice mail.  With both Kayla and myself messed up we did not want to drive but yet we were very concern. So me made the decision to go check on him.  When we get there he was fine.  Some how he must have gotten confused and laid the phone down without turning if off.  He did not know.  Like usual now days he doesn't know who anything happens.  Again I take a risk for Dad that he would never take for me.  
When I was leaving him last night after checking on him, his words where "When you come out here like this at night you need to say something before you come in or I might shot you".  I told him I did but he did not hear me, nor did he answer. 
I did get his insulin taken back and got a full refund of $168 for CVC.
