do prefer the saying lol (lawl) or lol (el oh el) or lol (laugh out loud) actually i do wonder why people say lol out loud
nowadays, 'lol' no longer means any kind of laugh, it actually means nothing, or maybe just a polite smile. so for that, i usually don't write anything. however if i wish to convey a genuine laugh, i might use something like 'haha' or 'hahahahaha', varying in length depending on how much i want to laugh
