Need help please...It's urgentwhat is the main problem of the story... What Do You Do With A Lost Unicorn? Written by Katie Thompson-Chapter 3

By the time we have managed to pull the now snoring unicorn out onto the driveway, the color in Joe’s face completely gone. “How…Where…Did this thing come from?” he asks, panting.
“What, afraid it’s real after all?” I ask.
He looks up at me and offers a half-smile. “Who wants unicorns to be real if they look like that?”
I hide a laugh. “Well…Now we just have to figure out how to wake it up.” I poke it a few times with my foot, trying to keep some distance. It just keeps snoring.
Joe shrugs and bends down next to its ugly face and starts jiggling its shoulder, like he’s trying to wake up a very old uncle.
Suddenly its eyes open wide, and with an unbelievable grace, it stands upright. Joe jumps away to give it space, and I just keep staring at it. It walks over to the desert-style landscaping of my neighbor’s side yard and being perusing for its breakfast.
“That thing’s a lot more agile than I imagined it would be,” Joe says. We both stare at it as it saunters around, pulling up the grassy weeds from between the rock mulch. “So…that’s a unicorn.”
I look up at Joe and he's got this silly grin on his face. It's just so 'Joe' that I giggle. “Do you believe that's what it is yet?” I ask.
“I could if I wanted to,” he replied.
I looked up at him, questioning.
“That thing,” he points to the unicorn. “I could believe it was if I wanted to.”
The unicorn seems to have decided that it isn’t going to find anything worth eating here and starts to walk down the sloping back yard to the next street. It looks almost like it belongs there, like a stray deer who often grazes around this part of town when no person is awake or watching. When it disappears from our sight, I feel like a ton of responsibility has been lifted from me.
The whole morning seems almost trivial. “Well,” I say, “I guess that is that?”
Joe shrugs, checks his watch, and motions toward the bus stop. “We should get going,” he says. I grab my bag, and we walk down the driveway.
“I don't know if that thing was a unicorn or not,” he says, looking up into the sky like he might see a dragon flying around to confirm my claim. “But I'm glad you called me this morning.”
“Sorry I was…not very nice,” I say, hesitating.
He laughs a little but keeps looking around. Then with a huge gulp of air, “Do you believe we could be friends again? Like, real friends again? Because I gotta say, I really do miss you, Anna.”
I smile, remembering what he said earlier and reply, “I believe we could if we wanted to.”
This time he looks over at me. “…And?”
“And I really hope we want to.”
