What do you think about workplace relationships, where two coworkers are dating.
I actually think it is fine it the people in the realtionship can be professional at work.
Yeah I think you are right. Definitely no PDA while at work.
I think it would be hard to work with someone after you've had an argument also.
True, workplace relationships can impact a worker's ability to succeed.
I used to date a guy I worked with. We also lived together. It was too much. I quit.
Did you quit the job or him? lol
The job first. Him later lol. 
Hah, that's funny. Workplace relationships can lead to feelings of loneliness so I don't blame you.
