You’re still taking to people, just not having them hear: just see. If you’re unruly in real, then rather keep that away from hurting others with unwanted comments. If you think it’s cool, boy, do you have a big thing coming your way. If you have nothing nice to say, don’t say anything at all.
If you’re going to swear and be rude, then rather keep quiet, if you don’t mind. Golden Rule for each and every human: respect, respect, RESPECT. One way is just to have common courtesyand consideration for others.
It’s not that difficult, really. Just give it a try and see even how much happier you’ll be. =)
