If not birthday AND not free--> don't do coke.

Contrapositive is "if you should do coke---> birthday or free.

that sounds right, thank you!, sometimes I have a hard time interpreting sentences that are similar to this,

for example:

only do x when y

Since only is before x and when before y, why isn't it y--->x for conditionals?
