Only for text when the technology was brand new like 10-12 years ago. Even in modern texting exchanges, no one does this.

no that is for texting only you might hear G'NITE S'YA AN'U

Not really. You might do that as a shorthand if you were texting a friend, but i dont know anyone who still types like that. My sister used to text like that but it made every conversation take twice as lomg because i kept having to ask her what she was saying :)

Only children and teenagers on social media

Thank you all for your information !
