Perseverance is...

I walk into my room and find a blown-up whoopie cushion laying neatly on my bed. I then search the house for Kells Bells, because it occurs to me that I haven't seen her in a while. When she's nowhere to be found, I realize that she's been hiding in my room...since I got home over a half an hour ago. The girl's got stamina. For this reason alone I "absentmindedly" sat on the cushion for her delight. She didn't even let out a giggle. She stayed there even after the cushion, and only came out after I found her and yelled "boo!" Her mom asked how long she'd been in there. Her response: "a really really long time". I just hope it was worth it for her.
