Most of you seem to insist that there is no different between a Squib and a Muggle, but that is not accurate.
If a Squib was the same as a Muggle, then Mrs. Figg would have never seen the Dementor that had attacked Harry and Dudley. She did/Dudley didn't, and she's a Squib/he's a Muggle, so, henceforth, Squib ≠ Muggle.
Now, this makes sense, plus it also corresponds with what I said above. It seems that all Squibs have some latent bit of magic in them, but they simply don't have enough to actually perform magic like wizards do.Originally Posted by Carole
