i am a symbol for change or where a river greets the sea i am the fourth of twenty-four in english i'm the 'D'

I walk a road that leaves no dust, I trade in questions, doubt, and trust. I till no soil, yet in each mind I plant a seed, then step behind. My voice can turn a page of thought, From I know nothing to I’ve fought. I hoist no crown, yet day by day I polish futures, word by ray. I hold no reins, yet gently steer Those lost in fog toward somewhere clear. I carry maps that none can see, To guide you where you choose to be. I vanish when the summers bloom, Return with bells in autumn’s gloom. I am the lantern on your track, The quiet mentor at your back. I am the sculptor of tomorrow’s youth, The steady guide of hidden truth. Called many names in every land, What am I, who shapes by hand?

When I'm in a room, I must be addressed, I stomp and trample when I get stressed, Me and your piano are rather alike, Hefty, beloved, and shining ivory white

I live in pairs but lose my twin, A lonely life I often spin. In drawers I hide, in shoes I stay, I travel miles but never stray. I hug your foot from heel to toe, Through heat or cold, through fast or slow. I catch the sweat, I fight the chill, A silent helper, calm and still. In washing drums I twist and turn, Yet one goes missing, a lesson to learn. A mystery tale in every home, Where vanished partners love to roam. I come in stripes, in dots, in plain, In fluffy warmth or sporty strain. Pulled on quick at break of day, Then kicked off tired and tossed away. No voice have I, no eyes to see, Yet life feels better because of me. So tell me now, be quick, be slick, What am I, soft and snug and quick?

I am not hate, and I am not love. I do not push, and I do not shove. One foot in, one foot out, I watch the world pass by about. I stand nearby, but never explore, I don't care to ask for more. What am I?
