You say: “I’m eating a sandwich later.”
Non-sandwich-eating person hears: “I’m eating sandwiches until I get so full I throw up.”
You say: “I had a sandwich last night.”
Non-sandwich-eating person hears: “I ate twenty sandwiches last night, and threw it all up and now my throat hurts and my stomach is killing me.”
You say: “I enjoy sandwiches.”
Non-sandwich-eating person hears: “I like to eat a sandwich every minute, and do orgies every other day. Once a week I bite a head off a bat and offer it to Lucifer.”
Now replace “eat a sandwich” with “drink a beer”, and you will understand the sanctimonious bullshit I have to put up with.
