it's funny but also frightening that younger generations' slang follows a trend of being reduced to 3 or 4 letters. Delulu is an outlier at 6 whole letters, but you can see the mental laziness that resulted in it. These idiots are going to be in charge of a burning planet one day and won't even be able to read the reports of the minds that came before them. It's scary to imagine being alive when they're in charge.
I'm not sure if reading comprehension was taught at your education institution (did you attend one? :?) but nobody generalized an entire generation based off of pop culture. You might consider returning to them and asking for a refund, assuming you paid anything for it. Tata :)
