Just as friends

I had a 50+ yr old patient in a couple days ago.
She comes in with a support worker and she lives in a group home.
She has downs syndrome.

Most of the time she falls asleep in the chair.

But this day she was super excited and happy and funny.

She kept telling me that she liked me. Then would tell me again because she forgot or she just likes to repeat it.

Part of the convo went like this:

P: "Heyyy, I like you, you know. "
Me: "Aw how nice, I like you too."
P: "Just as friends, okay?"

Some reason I thought this was funny.

Me: "yes, just as friends."
