Stop using LOL. And stop using every variety of the whole “laugh out loud” idea. We criticize so many people for using “um” or “ah” as fillers in their speech, but we openly encourage the use of lol as a filler. It may be that most people assume that it is slightly more intelligent sounding since it is an acronym, but it isn’t. It is just as frustrating. Using lol is simply a way to respond when you don’t know how else to or to fill up space in a text or conversation.
If you don’t have something intelligent or heartfelt to add to the current conversation, don’t use lol. Change the subject or don’t add. People won’t see you as rude, especially if you do add to the conversations that you feel passionately about and have the energy.
