No excuse you should always be helping your peers.
Nate I am very disappointed to hear what you have done to one of your peers. When you asked for my help I helped you and you should do the same for others. If you do not help him I will make you pay me back what you owe.
But sir I have so much to do and can't take on anymore work.
Nate on the phone with his peer...
Hey man I'm sorry about earlier I was over whelmed and wasn't thinking about the way I treated you. I will take your shift next week so you can visit your family.
