Mr. Hoodhood in The Wednesday Wars by Gary Schmidt, is not a very appealing or sympathetic character. He is Holling's father and is not a very supportive man—much more interested in his own life and concerns than those of his son, he isn't much of a father to Holling, especially while Holling is in junior high which is a tough time for any kid.
There are several examples that support this assessment of Mr. Hoodhood. First, Holling's dad says he will take his son to an autograph signing by Mickey Mantle at the Baker Sporting Emporium; this happens to be the same night that Holling plays Ariel in local Shakespeare Company Holiday Extravaganza's presentation of Shakespeare's The Tempest.
While preparing for the performance, instead of encouraging his son...
...his father tells him to wear [the embarrassing costume] to please Mr. Goldman, who might one day need an architect...
In addition, Holling's dad (and mother) does not attend the performance in support of his son. Instead, he stay home to watch the Bing Crosby Christmas special on the television—but at least Holling's friends come to watch. When the play is over, his father is not there to take him to meet Mickey Mantle as promised. Holling runs to the emporium, only to have Mantle tell him to get lost because he is wearing tights, and Mantle won't sign anything for a boy in tights. Had Holling's father been there, the experience would have been decidedly different.
When Holling and Meryl Lee plan a date, and Holling doesn't have the money to take Meryl Lee out for "dinner and a show," instead of contributing, Mr. Hoodhood laughs, saying that if he gets the contract for building the new junior high (instead of Meryl Lee's dad), Meryl Lee's father's business may well go under (or be destroyed).
Although being a good father should be his most important concern, Mr. Hoodhood is more interested in his business and himself than his son.
