They say it is because they don't want to let you down or hurt you;
but it's because they don't have the maturity to step up and
to be accountable to someone else. Usualy it is because they are self-absorbed and don't have their own shit together, so they use your feelings as an excuse.

Joe: "It sounds like the dude can't handle responsibility."
Prosperity is individually different and therefore a generation cannot fully guarantee and protect the next generation's prosperity.
A conflict of interest arises between the two generations. The conflict is solved by the death of the previous generation (natural or not)
which ensure that the future generation can manipulate their own prosperity more effective.This in turn maximizes the potential rate of evolution.
This is why intelligent people can be as irresponsible as your average idiot descending from
Ineffective natural selection or as irresponisble as the average defective inbreed local trash in your town.
With this in mind i hope you will be more responsible whoever you are.
