Imagine their family habits!
Tibietch families have very particular routines, construct elaborate nests and take great joy in sharing special favorites with their partners and their young. Every Tibietch family forms its' own unique sub-dialect of internal 'household' quotations, similar to the Tamarian language, which could be understood by outsiders, but only after copious observation and explanation.
Tibietch parents are at once strict on matters they consider serious and indulgent to the point of decadence on matters they either consider critical to their offspring's growth or which they recall strain in being a hardship to their own achievement. This is how it is possible to discover young Tibietch who are in possession of more resources than a majority of their same-aged, different-species peers, but who have had the freedom to learn by trial-and-error how to use them wisely and thus can be trusted with same at a precocious age. Many young Tibietch are situationally very sociable, however, and adapt well using surprising material or skill-related choices to manage situations like sensory overload, misunderstandings and frustration. They are often oddly popular in mixed-species youth communities and frequently well-respected among their peers when a challenge faces the group which requires expertise in one of their known special interests.
This was not the experience had by most adult Tibietch, needless to say.
It is now not uncommon to discover Tibietch parents in mixed-species youth spaces, either observing or even actively participating. They may be very quiet, startled at how different things are now, or they may be central to the proceedings, as the diverse offspring have requested 'storytime' or 'show us how to-' or 'can you teach us how-' and it is a rare Tibietch who can resist such things.
Sometimes, it is even possible to find a Tibietch parent, its' baby, and as many as twenty other offspring, including some other, unrelated Tibietch, gathered into a massed group hug which was not the adult Tibietch's idea at all.
