There is a light at the end of the tunnel.

My dad was a lead by example type of dad. So, his advice was scarce but powerful. 

I came home one day after work, ranting and raving about this "difficult" customers. Beside myself about this man's behavior. Full blown out ranting "bitchy waiter mode". He looked at me and said:

" Do you F*&#K this man?"  

" What?!!" My dad never swore. I stared at him. Shocked and bewildered.

" You don't fuck him, you don't do his laundry, you don't love him. He is not your problem. Someone lives with him, someone washes his socks, serves him his TV dinners, someone loves him. He is their problem, not yours. You only have to deal with him for a few hours, tops. Someone has him for the rest of his life. Willingly. There is a light at the end of your tunnel. "

He continued."As long as you are complaining about him, he owns you. Trust me, he is not at home telling someone about you. He is not paying you anymore. There is a light at the end of your tunnel. Look at it. "

Now, whenever someone is challenging, or difficult, I just think to myself... You are not mine. I don't live with you.  I see the light at the end of the tunnel.

Dad. Boom. Done. Love you.
