Married once, screwed my life..... Bachelor now... Are you single....? Am up for a date 🤣🤣

Don't you use lift in your office?

I have tried almost everything, even thought of the worst days of my life, and remembered the teacher slapping me in school, tried remembering the person I hate... Nothing works...
