Online interactions

I have this friend since I was on EP. I normally find very hard to speak on the phone or face to face so our interactions reduce to writing and some voice audios.
I have been feeling pretty shocked bc he got upset very easily and I neither could understand why. He has this stupid belief than guys don't use emojis a lot.
Some days ago, we talked on the phone and he seemed so different. I see now how badly I was missunderstanding him.
