Steve Urkel wrote the characters in the fictional book he wrote that had similar personalities to the Winslow family in the season 3 episode FareWell My Laura he made Harriet and Estelle out to be mean cranky and unfriendly so is this how he really thought of them while on the show that they were always rude to him ???

Steve loved Estelle, and Estelle was usually the only Winslow who wanted Steve around, so no.

Yeah but Harriet was somewhat nice to him i wonder what made him write her as a unfriendly person, then he made Rachel have a urge for him so maybe he did have a crush on Rachel.
