jkp1187, I personally like my coffee that hot, as it will eventually cool. I don't like it served at a temperature that isn't much above tepid, because it will get cold.
Hot coffee is hot. It might be very hot. The little sip holes in coffee lids have caused me to burn my lips with coffee that didn't actually burn without use of the lid, because of focusing... Should I blame the lid manufacturer?
Knives are sharp. I've cut myself on knives...
You can look at it as being snarky; I look at it as a matter of recognizing that some things out there come with anticipatable risks.
And while you might say, "she's a 79 year old woman," as though that means she should be viewed as more vulnerable, you might also say "she's a 79 year old woman," as though it means she should be that much aware - due to her age and experience - and that much more cautious, due to her (known) weaker physical condition.
You could also say that choosing to eat or drink while driving brings with it a certain amount of elevated risk. Go to Germany; cars there do NOT have cupholders. The Germans, strange though it may seem, think that a driver should focus on driving....
