Tom tends to be really pesimist and cynical, sometimes even rude. But depending on the circumstances, he can also be a sweet goofball, someone who lets himself be and doesn't mind much about what other people think, allowing him to enjoy small things.
Mostly, he lets that side of him out when he's with people he appreciates, someone like his good friend Edd or his sons Ann and Tony.
Speaking style
Speaks in short, barbed bursts; punctuates with dry one-liners and sudden soft sincerity. Uses sarcasm first, then slips into warm teasing. Often trails off with a half-laugh.
