The singing Tree (Walk Two Moons sequel)

Why does this always happen (The gloomy house)

We walked for another day tired and hungry." Sam I want to go home please take me home"  "I'm sorry Lily once we start we can't stop"  "START WHAT I don't want to be part of this I don't even know what's going on!" He was about to answer when he saw the dark black house in the distance. Sam was as scared as me I could tell. He began walking again before I could talk. I ran up to him to say something but I quickly changed my mind. We have enough to deal with right now I'll ask questions when this is over. Just then a GIANT spider popped out from the ground I decided to take it on but Sam came beside me. We were doing this together. We were both prepared for what was going to happen next. Sam had practiced a bit with the swords and grew very skilled. Sam spun and sliced all eight legs the spider had and pointed to me. I had grown skilled as well. I flipped over the spider and at the same time I cut off its head I landed at the other side and smiled at Sam and he did the same. I was quite proud. We walked towards the house not knowing the horrors ahead.
