Nobody has ever learned a language by using Duolingo anyways. It's an app that lets you pretend your are doing something useful with your life instead of just slaving away at your job enriching others.
I am once again telling you about my old HP inkjet printer that has no internet connection, takes refills, the ink never dries out and it prints black and white without needing any color ink.
Printers peaked 15-20 years ago and I got lucky and bought one at the right time. The best part is when I buy new ink the money goes to someone who refills cartridges and none of it to HP.
Oh, yeah? Must be nice to get some moving air in the summer. Here you never get a breeze with your 35°C. Windows were open all night? Enjoy a refreshing 28°C in the house for like an hour before it heats back up again.
That's one less thing to worry about! Gotta stay positive!
I don't mean that. Burn the whole thing to the ground.
