People I know from work are work aquantices. Some I have been rather fond of but at the end of the day friends are people I hang with when im not working. I personally have not had work friends. Its like friends vs schoolmates. I have had friends that were also schoolmates but plenty of schoolmates that were not. Again not that I did not like them or that I did not share a laugh with them here and there but it comes down to hanging outside of the required to be at thing.
