Lack of self-awareness in The Caretaker is shown mainly through the character of the tramp Davies, who appears not to realize just how offensive his racism or his ingratitude to Mick for offering him hospitality really is.

Indeed, lack of self-awareness is one of Davies's most notable characteristics. No sooner has Mick let him stay at the flat than he's criticizing his generosity. The tramp's ingratitude can also be seen in his turning down not once but twice an offer by Mick and his brother Aston to be the flat's caretaker.

Davies's reason for turning down the offer—he claims to be worried that someone might track him down—is completely absurd and once more shows his lack of self-awareness. If Davies really were self-aware, then he would know just how ridiculous he's being.

When Davies indulges in racist comments about the next-door neighbors, he gives the impression that there's nothing wrong with such hateful remarks. It's as if he's so lacking in self-awareness that he cannot conceive that anyone would be offended by him.

Finally, we have Davies's firm, unshakeable conviction that getting to Sidcup, a pleasant, leafy suburb in South East London, will be the answer to all his prayers. This shows Davies to be blissfully unaware of his incorrigible laziness and lack of motivation.
