Ok, I have a colleague that thinks carrying around a container of milk will help him gain weight. He is a pretty lanky dude and runs marathon. So it only makes sense that he is a skinny thing.

How do i tell him nicely that carrying around milk and drinking that all day is a dumb idea.

Dunno, if he is even worth my time. Because this same dude said he couldn't make it into work because he got a herniated disk from dead lifting. When I heard this I was highly doubtful. But what do i know.
