This is an injunction where the child can be treated as a grown up or their free child energy is squashed by being told that certain play or fun is silly.  It is difficult for parents who have experienced a serious childhood not to convey as long as you act sensibly you are acceptable.  Engaging in free child, or natural child energy is something that is part of ones socialisation process in development and if this did not happen having fun can be uncomfortable.  If you feel awkward relating to children you may carry this message within yourself,  This can also be conveyed magically by a child who  told themselves they need to parent their little sibling.  In some families if a child is having fun it can be considered lazy or irresponsible.  Individuals with this injunction often feel stiffened up when at parties or certain gatherings.  Or don’t get mindless humour and judge the waste of time “past-timing” is that some adults may partake in. This can include hobbies, sport or social engagements.  They may not be able to enjoy trivia or just” Being” but feel a need for having objectives on a daily basis.  However, being a child all through our lives at times is important for free child energy release which keeps us balanced and can feel joyful.  Otherwise individuals can find dysfunctional ways of engaging in this.  In addiction i have seen individual journeys of using alcohol to loosen up and not be able to engage socially unless lubricated.  This can be because the alcohol can get rid of the critical parent in ones head that holds the negative messages.  Or the individual who works so hard and is always responsible and in a parent role needing a substance to get away from the pressures of the expectations they hold inside.  This is why looking at injunctions is personal inventory can have a impact on ones awakening to self.
