to be honest, in high school i unironically typed to my crush like this because i felt shy and it felt like talking quietly... ^^;; i also really liked ellipses... and this smiling-embarrassed emoticon, which i had a tendency to use more than once per message ^^;;
Here in Germany we have something called "Groß und Kleinschreibung" if you make a mistake and write a word small that should be capitalized then you are immediatly unattractive.
