This is why IT people have a bad reputation in the world of socially adjusted adults.
BTW "master/slave" words don't even make sense for databases. They are "authoritative / possibiy-stale-replica". In many setups, the master doesn't care if the slave exists-- this is an important feature to protect the master if the slave fails, avoiding "many points of failure"
In IDE cables (remember that case, from Oakland CA a few years back?) master/slave means something different again (but I don't remember how IDE works -- it was something like primary/secondary,though, not one controlling the other)
