Redundancy

Fuck, it doesn't make sense, one minute a person is there, and unless they're there 24/7 how can you expect to rely on them when they want to be relied on? If you want to contact them, the idea of chasing them shouldn't come into question, they should be there, so the act of chasing doesn't exist? So for then someone to offer reassurance by saying they'll be there will be redundant, and in fact by insisting that shows guilt for not being there, because regardless of what they say, I would know they're there if they were there?
