When us Gleeful's make deals.. We always keep our end of the deal.
That was something the Gleeful's had said through the centuries, no one from what they knew has EVER broken a deal. Not even once, Mason usually made deals with your mother though every time she wanted him to help showing off how "good" your father's abominations were.
Stan and Ford, your great-uncles as well as Mason's and Mabel's, did their own things that made the family even more rich and famous. Ford conducted research on other witch covens as well as oddities that laid within the town such as demons, fairies, and other species that seemed to be well-known but not all that well-known throughout the town of Reverse Falls.
Stan on the other hand, he ran a show named "The Tent Of Telepathy" that starred both Mason and Mabel Gleeful as the magicians. He even ran the Mystery Emporium that was close by the tent, as well as near the Witch Academy, so that earned the Gleeful Family a good fortune especially with what your parents do.
Matthew Gleeful, he build abominations that are security defenses for the general public to purchase for their homes. Caitlyn Gleeful, she persuades and shows off the abominations every Friday at the Gleeful Enterprises building to sell the abominations to gain profit with her husband. Most of the time, Mason will "play pretend" to show how powerful and good the abominations were at their job to impress the audience even more to get them to sell.
Mason and Mabel, they were stars of the Tent of Telepathy. Mabel was incredible at Grudgby, she was the captain of the team after Mason had quit the sport when he was captain. Mason, however, he was the top star student in the abomination track, he was intelligent and was popular like Mabel in the Witch Academy.
"Move it, Geek. Mom wants to talk to us." Mabel said as she gestured for you to get up from the couch, your parents waited for the three (or two) of you to enter the glorious living room you all had.
