Lyrics to NUMB by Linkin Park?

I'm tired of being what you want me to be Feeling so faithless lost under the surface Don't know what you're expecting of me Put under the pressure of walking in your shoes (Caught in the undertow just caught in the undertow) Every step that I take is another mistake to you (Caught in the undertow just caught in the undertow) I've become so numb I can't feel you there Become so tired so much more aware I'm becoming this all I want to do Is be more like me and be less like you Can't you see that you're smothering me Holding too tightly afraid to lose control Cause everything that you thought I would be Has fallen apart right in front of you (Caught in the undertow just caught in the undertow) Every step that I take is another mistake to you (Caught in the undertow just caught in the undertow) And every second I waste is more than I can take I've become so numb I can't feel you there Become so tired so much more aware I'm becoming this all I want to do Is be more like me and be less like you And I know I may end up failing too But I know You were just like me with someone disappointed in you I've become so numb I can't feel you there Become so tired so much more aware I'm becoming this all I want to do Is be more like me and be less like you I've become so numb I can't feel you there I'm tired of being what you want me to be I've become so numb I can't feel you there I'm tired of being what you want me to be


What is the difference between a riptide and an undertow?

A "rip current", the proper term for riptide, is a current of water that can knock you off your feet and carry you a distance out toward the sea. It is formed by breaking waves where the water that returns back out to sea from either side of the current converges. Water from both sides of the rip current rushes back out in one place. Often you can see them. They do not drag you underwater. To escape it, don't fight it, but swim parallel to the shore until you are out of the current, then swim back to shore. If you find yourself unable to reach shore, wave your arms and yell for assistance. An "undertow" happens when the waves are breaking strongly, one on top of the other before the first wave has a chance to receed. A large volume of water builds up and the wave underneath goes back out forcefully while another wave is coming into the shore on top of it. To escape it, do not panic, and do not fight it. You MAY quickly make contact with the bottom where you can push off with your feet to reach the surface. But in most cases, an undertow will pull you under the watter and, quickly take you km's out to sea (Because they often happen on beaches with a deep and quick dropoff) If you miss the signs and get caught in one of these, your best defense is to know what to do, stay calm, and know how to swim in the surf. Surf swimming and pool swimming are different. If you are not a strong swimmer, swim with a buddy in a lifeguarded area. The lifeguard can often tell you where the rip currents are.

How does a beach sand move along the shoreline?

It moves it in a zig zag motion. The waves go up the beach in an angle, so when the waves breaks at an angled the pebbles/materials are carried up the beach in the direction of a wave (swash) and when the wave returns to see dragging some materials back with it called a backwash.hope this helps
