*calls grandpa I don't usually talk to that much to congratulate him for his birthday*

*grandpa picks up*

*congratulates*

Him: so, I know that you study CS and I was working on something [Word document at the moment] and my letters keep getting different sizes! Sometimes they're small, sometimes they're big, sometimes they're in between! I have to erase everything everytime because they just get messed up every time!

Me *sighing, but confused because upper-case and lower-case are the same with "big letters" and "small letters", respectively, in my native language: have you checked Caps Lock on your keyboard?

Him: What is that? I have Esc, 1, 2, 3,... (proceeds to read me the keys on the keyboard)

*explains where caps lock is*

Him *gets angry*: no, you don't understand, sometimes they're small, sometimes they're big and sometimes in between! Caps Lock doesn't solve it! *proceeds to read the keys from the keyboard again*

*thinking that maybe it's the font then, asks about the Word version, to know what to point him to*

Him: WHAT? Word? No! I'm using my keyboard! What don't you understand! I explain to you and you have no idea!

Me: well, I'd need then maybe to see the screen

Him: I'm so angry with you, you say you study so much but are not even able to help me with such a small problem. I'll just find someone else. Thanks for your wishes *hangs up*

And this is how I only tried to congratulate my grandfather for his birthday but turned into a "failing" tech support. I just wanted to be a good granddaughter
