T-Rex: Here's how to give someone a gift: just give them it! DONE. It's nice to be nice! PROBLEM SOLVED.

God: UH NO WAY T-REX IT'S MORE COMPLICATED THAN THAT
T-Rex: Explain!

God: WELL FIRST THERE'S TIMES FOR GIFTS AND TIMES FOR NOT GIVING GIFTS AND IF YOU CHOOSE POORLY IT CAN BE EMBARRASSING FOR EVERYONE
T-Rex: How is there a "time not to give a gift"?
Dromiceiomimus: Oh, tons of times. During a funeral. In front of other people if some of them are getting gifts but one of them isn't, because then that person will feel bad. It's complicated!!

Utahraptor: And that's not even considering the politics around it!
T-Rex: POLITICS?

Utahraptor: Give a gift that's too expensive and you could be seen as showing off your riches, PLUS you run the risk of making the person uncomfortable by indicating that you like them MORE than is either acceptable or reciprocated!
T-Rex: Oh dang this sure is complicated

God: YEP THAT'S HOW COME I GAVE Y'ALL THE GIFT OF LIFE AND THEN STOPPED I DIDN'T WANT TO BE GAUCHE
T-Rex: Didn't you ALSO give us dominion over all the animals too?
God: HAH HAH HAH
God: NO THEY'RE JUST BIDING THEIR TIME
