Did someone teach you that you should always put a comma before “too”? They taught me that, too. Or, rather, they taught me that too.
Comma. No comma. Whichever.
This is a tough one for me, because putting a comma before “too” is almost second nature at this point. Leaving it out feels like omitting bananas from my cereal in the morning: You can eat the stuff, sure, but it’s just not the same. Something feels like it’s missing.
