The handling of a Facebook status is tricky business. Facebook users should therefore beware; impulsively commenting on a friend’s status can lead to sticky situations. If you aren’t careful, your two cents can put you in some rather awkward situations.
Here are five kinds of Facebook comments you should avoid posting to your friends’ statuses.
Sarcasm. Your friend writes about the terrible day she’s having or the great meal she’s just ate. Writing, “lol, loser” or “fatty!” under her status is probably not going to sound very funny in her head when she reads it to herself 
Good sarcasm relies on tone, facial expressions and sometimes hand gestures that contrast with original statement. So save the sarcasm for in-person encounters, and even then, you may want to think it over first.
Berating. A friend posts something hurtful or offensive as their status. This can make you want to put this person in his place or set the record straight. However, you may want to re-think using his status to take said measures. Not only does it embarrass the original poster, you can come across as trying to publicly shame your so-called friend. Instead, shoot a private message to his inbox explaining your discontent.
Arguing with a friend of a friend. A friend posts a debate-worthy status or link-probably about religion or politics-prompting you to chime in. Then, someone you don’t know responds to your comment. Oh boy! This is interesting and fun until things get heated and the person impolitely disagrees or tries to argue with you. This puts the mutual friend in the very awkward position of having to defuse the situation or possibly choose sides. Do your friend a favor and don’t argue with her other friends-instead, end the conversation or don’t respond.
Not getting the joke. A friend posts a mysterious statement that, without context, seems out of character, strange or alarming. You then respond, expressing your concern or confusion about the vague status. Little do you know, the statement is simply a quote from a popular film or a reference to an inside joke. Too late now, deleting your ignorant statement only highlights your incompetence and general lack of pop culture awareness. Next time, be sure you know what the person is talking about before you embarrass yourself. Better yet, suggest the person start adding quotes to, well, quotes.
Denying validation. A friend posts a depressing lament or something rather self-deprecating, secretly seeking supportive comments and validation. Good friends respond with uplifting advice and words of encouragement. Bad friends become annoyed and frankly tell the poster to get over his self. Validation seeking is not always easy to spot on Facebook. It’s still your job to determine whether or not the poster is simply sharing, or looking for someone to approve their opinions, choices and tastes. Aren’t sure? Take your mom’s advice: If you don’t have anything nice to say, don’t say anything at all.
