Just arrived in a shared accommodation for the first time ever

I JUST arrived here like 20 mins ago, and I am SHOCKED by how dirty the kitchen is. Apparently there are 7 other people living here. This is my first time living alone, and that in a shared accommodation. These are all grown ass people why dont they clean up after themselves?? I dont get it?? There are fucking roti pieces on the kitchen counter. The lease is 6 months GOD SAVE ME
