I lied and got someone fired.
Why would you lie and get someone fired?
That someone was acting like an asshole every time I saw her.
Getting someone fired is not a great thing to do. Remember that these people have families who are relying on them to provide.
It's not really my fault, if you really blame anyone there's that manager why didn't fire her.
It is not mature to attempt to blame someone for them being fired. Taking responsibility for your actions truly shows maturity! I know you are mature.
