Take us down and all apart/ cherry tree/ lay us out on the table - go ahead and make us tell the truth. could be about one lover in a relationship who was "with" another, and is trying to hide what they've done. the cherry tree represents honesty.

You're sharp alright - The one (or many) he is hiding his actions from is extremely smart, and has already picked up on what is going on behind his or her back...and now they're trying to figure it out.

But no one is asking so leave it alone/ leave it alone/ can we - the narrator wants to leave it be. could be because he doesn't want to admit what he's done, but he could also not want to speak about it because then it makes it a concrete issue. it may also solidify feelings and emotions that he's otherwise trying to ignore/hide. "Can we?" seems to question if they'll be able to just let it be and keep going forward with their secret, or if emotions will get the best of them.

loose lips sink ships - if they do speak about it, and bring the problem to light, then his relationship will be destroyed and his situation will get even worse.

don't look at me/ i'm only breathing/ don't look at me i'm indiscreet - the narrator is getting paranoid, thinking that his significant other is going to know something is wrong just by looking at him. by saying "i'm indiscreet", it shows that he's lacking confidence in his ability to hide his emotions and is afraid that his lover can see right through him.

can we show a little discipline/ can we - the narrator wonders if he'll be able to show restraint and not make the same mistake twice. however, he's questioning his ability to control his feelings, wondering if they may be too strong to hide forever.

i also agree with SimiC on the gossip interpretation... that makes a lot of sense as well.
