What do you think of people who type cngrtzzz, hpy bdy ? Do you find it offensive?

Gone are the days when people type in abbreviations while texting. It was way back in 2008 to 2013 when people were still sending sms and typing within a character limit that people typed liked this. I found this girl who texts this way even now. Honestly I find it so irritating. Just imagine someone wished your birthday with a message like 'hpy bdy'. Why did you even bother? I mean it's not even hard to type these days with keyboards that finish the word for you.
