How do I never know what I want when my mom asks me to write a Christmas list?

All year I go "man this would be awesome to own" and I even write myself notes but when she puts a list to be filled out I'm just like "uh... hurr... durr?"

lmfao me too

I'm just like OH, I DON'T REALLY WANT ANYTHING

and then five minutes later I'm like WAIT FUCK
