I wish they just responded with a full lore dump that would be far more confusing

"Yes mom, I'm sorry to tell you I'm part of Thanos' army now. He is traveling planet by planet to erase 50% of every global population. I think it's really smart. You might disappear though, but it's all for the balance. Once we kill those pesky Avengers and collect all the Infinity Stones we'll be right on our way. Sorry, can't talk now, hope your phone is charged over 80%, busy busy. And thoughts and prayers that you're part of the 50% that remains! If so I'll call you tomorrow after we kill Spider-Man. Love you."
