Here’s the thing: words get twisted all the time. Even if you think something you’re saying is innocent and not prone to start drama, it’s possible that it sounds worse than it is. If you’re not sure, just think of how you’d feel if you heard someone say the same thing about you.
In the vast majority of cases, an issue you’re having with a friend should be brought to them directly (or let go of, if it’s something minuscule). If you just need to rant, a trusted family member is the perfect person to go to; that way, you can release your frustrations and move on, instead of causing drama and talking shit.
