What are some warnings that you have ignored in the past?

When someone said they were an asshole and I didn't fully take heed to that, and blindly believed in his good heart he wasn't ready to own up to yet... When some tells you they're not a good person, that they admittedly tell you who they are, don't turn a blind eye to that. They've volunteered the cure, a way out, and you only end up poisoning yourself for not investigating those flags...And taking action to leave them. But lessons have been learned, and I've sternly applied them. Look before you cross the street! Lol😂
