As I settle into my 40's I stopped tolerating:
Young cats playing their music loud out their phones. I was on the subway in NY and I literally gave this dusty youngin the deathstare, and 'I told to get some headphones or turn it off'
I stopped lending out money to friends and family for the most part, if you need 5 or 10, cool, but anymore than that and I gotta put it in writing that you gotta pay me back.
Negative people have no place in my life.
Breh, been stopped doing that. It must be life or death by my determination

of course. At this point, they know its useless to ask.
Yerp, b. Had to call and speak to my gym's manager because of an employee's constant rude behavior. Bish get another job if you're not happy with this one!
Ive grown to not tolerate sitting around smoking blunts doing nothing. I smoke all day every day but I have no time to sit around with the homies bullshyttin. Id rather give you a blunt to go than smoke with you wasting time.
Ive grown to not feel the need to defend myself. If you dont understand me or what i do or how I live its not my problem. I speak plainly so I dont have to explain what i said. You just want a different answer.
Ive grown to not feel obligated to help those who dont help themselves. Ill meet you halfway. If you do nothing, neither will I. I used to be the pit bull of the crew, just point me in the direction to attack and id be locked on. Now that ive grown ive learned that you cant go harder for someone than they will go for themselves.
One thing I have learned to tolerate is most people are going to disappoint you. So i dont put expectations on people anymore, or try to push them to succeed. I simply accept them for who they are not who I think they can be or should be.
To the first point, I have had to come to this understanding as of late with myself. My wife's brother wants to argue over dumb shyt all the time and me, wanting to defend myself, would falter into a fruitless argument but I had to realize that breh has nothing going for him. He lives with his moms at 30+. FOH with your rhetoric as I have no time to convince anyone.
To the second point, I have felt this way for sometime now. All (and I mean
all relationships/ friendships, etc.) are temporary. "Friends" (and family) have disappointed me several times where, at this point, I have more associates than friends. The expectation is you will disappoint me so let's get this "declassification" paperwork rolling.
All sounds cold but it is a reality in my life. No wasted time and energy will be exerted.
