Very good.
I'll just nip off and shoot myself.
Couldn't I just have a green salad instead?
Oil makes it taste greasy. Yuck. If my choice was oil or nothing, I'd take nothing. Air popped popcorn is delicious, you get the fresh popcorn without the grease. As for salt, you get enough salt just with a sprinkle over it. If you want more than that, why aren't you just eating a bowl of salt instead of popcorn?
To each their own. Myself I like the chemical reactions that occur with hot fats and carbs. The key is to use an oil with a high smoke point so it doesn't burn. Those chemicals are not so good for you. Anyway, some will prefer the flavor of popped corn unadulterated by oil, butter, or much salt, and other prefer the tastes of fats and corn. Enjoy.
'for texting' is a prepositional phrase with the preposition 'for' and the object 'texting'. It takes a noun to be an object. 'Texting' is the name of an activity. Names are nouns. Note that I am talking about usage. As another poster stated, the word 'texting' has the form of a gerund which is a form derived from a verb that can be used as a noun. It can also be a verb. I am texting him a message right now. Some day that form may be recognized by the dictionary. Dictionaries don't establish language; they describe it according to accepted usage.
English is such a fun language. We can verbify nouns and subject verbs to nounification. Pretty soon, I predict there will one day be only one part of speech, the Interjection.
Wow!
