I rarely write a check, I do most of my bill paying online and I use PayPal for a lot of purchases, and my ATM card for most everything else. I have checks though, just in case.
My mother steadfastly refused to get with the technology. She wrote checks, hung up on automated messages, never pumped her own gas, you get the picture. Whenever I see someone writing a check, it reminds me of my mom, and how much I miss her, so I just sigh and wait patiently until they're done.
