LPT : Old people text in capital letters because it is easier for them to read it, keep it in mind when texting your older relatives

We was making fun of my wife's aunt because she is only in her 50s and quite tech savvy and she was the first to actually say - guys I text in capitals because I can read it without putting my glasses on. So we started texting them in capital letters as well and they are all really happy. Never crossed my mind that reason until then but there you go.
