User blog comment:1seddiefan/Does Mrs. Benson like Sam more than Carly?/@comment-3000214-20100914013708

I think it's because Carly has always been Freddie's object of affection for so long, she just assumes that Freddie's always going to chase after her and she's probably had to dealt with Freddie saying all these good things about her and what not but he doesn't love her anymore so... she probably hasn't payed more attention to Sam, i think, because while Sam causes Freddie physical pain (which can be healed with Neosporin and a band aid) Carly toys with his emotions and causes him emotional pain (for all the times she's rejected her). She doesn't consider Sam to be much of a 'threat' as in 'she'll ruin the Mom/Son relationship' at least not yet.. ;)
