Absentmindedness

What you see in the image are charred milk vessels all because I forgot that milk was on the gas. The charred smell drove me there.  The milk got dried up completely and the vessels were beyond retrieval. And this not once but several times. 

I am normally not absent minded but when I am on my PC I forget the world and the milk on the gas is the casualty.I no longer keep milk on the gas when I concentrate here. 

I had to purchase more vessels and thankfully they are all intact.
