This song came out during my first year of college. I'd already had my heart broken by my high school sweetheart so I thought I knew what it was like to get tossed around. (I didn't.) I related to this song right away because it spoke to the part of me that was still angry. A few years later I heard the acoustic version and liked it even better than the original. It still has the same strength in the lyrics but without the intensity of the electric instruments. It's also a little bit slower than the original, which I think works better for it.
Push has stayed significant to me over the years because I feel like I can relate to it at some point during any relationship: either I'm being pushed around or I'm the only doing the pushing. I've always liked the opening line "She said I don't know if I've ever been good enough, I'm a little bit rusty and I think my head is caving in. And I don't know if I've ever been truly loved by a hand that's touched me" because I've certainly felt like that at times. I think most people do at some point in their romantic lives.
This is yet another song that has gotten me through tough times because it reminds me that I'm not the only person to ever feel this way.
