Today, Lucy needs oxygen at night and while 3— one small good deed reminded Zwick how "4" she and her husband, Yuri, truly are.
"To the 5 in 2D. I don't know you, but I imagine you saw us 6. I was pushing a stroller （婴儿车）, had a diaper （尿布） bag on my arm and also 7 an oxygen machine for my daughter," Zwick wrote on her Facebook post. "We 8 the plane, sat down in our window seat and made 9 to those around us about having to sit by my yelling-but-happy baby. The flight attendant came over and told me a gentleman was waiting to 10 seats," she wrote. "You were giving up your comfortable, first-class seat to us. Not able to 11 tears, I cried my way up the 12 while my daughter Lucy 13! She felt it in her bones too... real, pure, goodness. I smiled and thanked you as we switched but didn't get to 14 you properly," the mom continued.
"So… thank you. Not just for the seat itself but for 15. For seeing us and realizing that maybe things are not 16 easy. For deciding you wanted to show a random act of 17 to us. I can't wait to tell Lucy someday. In the meantime... we will pay it 18."
