Every vowel except you

Me and my friends are walking now, along the road, we took a bus to
this location and from there we started this forward march.
I walk carrying your letters in my bag, the blue one that you always
liked and I remember when I first read them and what I wrote in
return.
I keep turning to my left to talk to you, but you are not there. No
longer by my side, walking with me on this endless journey. So now I
have to turn to my right to see the people around me.
Everyone is here, taking every step with me, everyone except you. There
was always a gap between U and I and now that gap is eternal, so now
everyone is walking again, everyone except you.
