I'm struggling to find the most appropriate word to describe the following type of remark (italicized), or the tone behind it:
"I wish I could talk to him right now..."
"There's this great thing called a telephone that allows you to talk to people, even if they're not in the same room. You should try it."
I looked at synonyms for "sarcastic" and "condescending" I found in the Collins, Roget's and Merriam-Webster thesauruses, but didn't see a word that implied both sarcasm/indirectness and condescension. Is there a specific term for this type of remark/tone?
