Cover art for Mouthful Of Cavities lyrics by Blind Melon

i believe he's speaking in 1st and 3rd person in the 1st verses. mouthful of cavities is a decietful and dishonest tongue. and a person like this reminds him how desparately he wants more (like true freindship). the feinds are the ones with the bullshit freindship or acquaintenceship. in the 2nd verse he's begging for more than this, and for these people to be true, rather than waste precious time, because in the long run who wants regrets, then he reminds himself that there are beautiful people in the world (his friend he loves to see smiling). and he misses that comfort. all the while, these fake people laugh while they watch him make mistakes and wait for him to fall again. thats my interpretation
