Many events have occurred in the recent past leading me to the following conclusion. A single person can unintentionally inflict an unbelievable amount of stress on people they interact with. We may become attached to such a person before we realize the effect they have on us. One's attachment to friends could force a connection, which may grow into a stronger relationship of some sort. The stress may build until it causes an explosion. Or it may not be until after separating ourselves from said person, interaction with said person causes us to realise just how much stress they did cause. It is up to each individual to decide who it would be best to involve in their lives. Sometimes that means blocking out people who you thought you enjoyed having around.
