I do not plan on splitting my bonus with a friend who was recently hired at the company I work for.
What is the reason why you do not want to share it with him?
I think I should be able to spend my bonus however I want.
That was nice of you to help your friend with the job. You don't have to split the referral bonus with them. They are probably appreciative enough of the help with getting the job.
I don't care I just want them to be miserable and they could just stick their heads up the anus. They can suck my dick.
The bonus was one that your earned, so you do not have to share it unless you want to. If you had promised your friend that you are going to share it then you should probably honor your word.
