Places to go and people to see

My mom bought a plant today. It's pretty big, it comes up to my waist. But she was still not convinced that it was tall enough. So she put it on this trolley thing we have, which gave it an extra 2 inches. She asked me what I thought and I didn't quite know what to say. It confused me... who puts a plant on wheels? Where is it going to go?

So it's about 2 a.m. and I just picked up the plant (trolley, too) and put it outside her bedroom door. When she wakes up, almost trips over it, and then asks me why it's there, I can just play dumb and tell her, "When you put a plant on wheels, expect it to go places."
