I didn't kasher my kitchen for Pesach because I knew I would only be eating a few meals in my apartment, since I go out for all the Yom Tov and Shabbos meals. When I got back in town from the first days of Pesach, I went downstairs to my neighbors to get my mail that they had brought in. My neighbor asked me what I was eating for dinner. I told her that I wasn't sure, but I would throw something together, probably matzah and cream cheese. She was making dinner for her family, and offered to make me up a plate also. A few minutes later, she came upstairs with a plate heaping full of really yummy food. And then told me that if I want any more, there's plenty. So, despite the fact that I don't have a kosher-for-pesach kitchen, I'm still eating really well, thanks to the amazing kindness of my neighbors!
Update - In case I was too nice to ask for more food (and what she gave me initially was plenty!) my neighbor sent two of her children up to my apartment to see if I wanted any more. So nice!
