Lyric discussion by TakenAptly 

To reply to Lally123, I'm fairly sure she means present as in the present moment, not present as in a gift or child.

Which is a pretty cool, noticing each moment becoming the present.

As for my own interpretation, the thing she cannot tell is that she's alive. She doesn't know how to explain life & feeling. No answer to the great questions of why we're here and such.. But he says you know it's good though, cause it's running you with red (blood) as kinda of like a symbol for life. (I forgot what those type of symbolisms are called v_v) So I'm taking it as he's pointing out.. we [her] might not know how to explain life, but it's in our veins.. we have the answer in us, we just don't know how to explain it.

Totally agree!
