If someone asks me to do something that requires me to remember, I ask them to email me, or I write it in a notebook. At work I carry around a notebook all the time for this purpose, and I often have a notebook on me out of work. I am reasonably good at processing paper and email, though not 100% by any means.
If it's too complicated to put in a scribble in my notebook, or I am lacking a notebook, I try to make it clear that I need an email. My memory is catastrophic these days (I still haven't really adjusted, though it's been catastrophic since sometime during my pregnancy, so at least 3 years) so if I can't write it down/get it written down for me I quite probably won't remember.
Also, if someone doesn't want it enough to write a quick email, they don't want it enough for me to go to effort on their behalf.
Some of my family have taken to sending text messages to ask me to do things, and I haven't quite got into the habit of processing text messages into my to-do lists, so this often fails or results in me getting nagged.
Because I am so unreliable about casual requests myself, I don't assume anyone else will remember ones I make of them, and in fact I quite often forget that I have asked, unless it's really important (in which case I will write a reminder email).
