Dead peoples things

I keep dreaming about my father who died about 10 years ago now. It's odd because I hardly think of him anymore. My dreams are always slightly different. In them he is alive and we are normally doing something mundane like washing up or DIY. They are always set in this time, these are not distorted memories. During these dreams I seem to know in the back of my mind he has died and time is short and precious.

I often wonder how many simple tasks we carry out with people who leave our lives and should we know would we pay more attention to that time. Lock it away or slow it down.  

 I cannot remember times I did these things with my father when he was alive but I'm sure we did.
