Is it just me, or is it virtually impossible to pop open cardboard food boxes along their perforations? I'm talking about mac & cheese, baking soda, corn starch etc...
That little spot on the top side that says push here to open. I can never get it to tear, usually all i do is cause the cardboard to buckle. And then I get annoyed and have to rip open the top instead. And my thumb hurts.
