Forgetful

Every time I go to the grocery store, I forget something.
I write lists on a magnetic notepad on the fridge.
But I forget a pen, and don’t mark things off as I get them, so I overlook things.
I tried a notepad app on my phone, but I’d forget to check my phone.
There was an icon-based grocery list program I used, adding and removing icons for things as I bought them.
Then, my sister-in-law distracted me with her constant talking, and I forgot things.
Now, I just get things through delivery services.
So someone else forgets for me.
