Why does Gen Z use initials to communicate? When they text me I get confused because all I see is hru, wbu, tbh, nd u, idk, idek, sum.

Perhaps they can't spell real words..... (Were they to busy sleeping in a school, hence Generation Zzzzzz...?)

Either that or their 'phone companies charge highly by the letter so making their umpteen-hundred-quid instruments too expensive to use in any literate sense!
