Bad parenting. Kids will always be entitled so long as we give them reasons to feel that way. It's pretty natural. Giving a kid a smart phone at an early age seems to be the mistake most parents are making. Access to the internet means access to everything. Then parents think taking all that away as punishment is acceptable and wonder why their kids get so upset and lash out. It's a travesty.
Funny you should say that about Squidward. Another friend of mine said the same thing just the other day.
The older I get, the more I understand why Spongebob is so delusional. If he let everything get him down like poor Squidward "2kewl4r00lz" Tentacles, he'd just be another average joe. Instead, he's SPONGE BOB "THAT ANNOYING SON OF A b***h WE WILL NEVER FORGET" SQUAREPANTS.
