You know, the people who really need to learn how to use smilies are those NTs that have the cynical, dry kind of humor (I've seen this kind of humor really much with NTs). This is because I don't know them as well as I should to get that they are most likely joking. IRL I like that kinda humor but here it is sometimes impossible to tell if it is a joke or not. My insufficient English skills of course don't make it any easier.
