I never seem to get my snacking right

If I buy Salty ones (yummm) then when I get home, I want sweet! If I buy sweet (yummm) then I want salty.
As I've been out sick for a few weeks, I'm now driving my family members crazy... they never seem to bring me what I want, once they're home... but! I think I've worked out a plan.... I'll send my brother out for salty snacks and ask my sister in law to bring the sweet ones! /nod. mmm, salt and chocolate... mmmmmm
