(a.) purchase a card or gift for you, mother,
(b.) the yet purchased card or gift would stand an iota of a chance of making it there before sunday. it's not like they deliver mail on sunday anyway
...so i just want to say now (and you should note) early, "happy mother's day."
if you want to tell somebody something, would you put that in quotes? anyway, you will have to check the usage of those quotation marks...
also, a note of curiosity that came up in my mind posting this...you know how people say, "happy early birthday," or "happy early mother's day"? it isn't right. the word early is incorrectly modifying mother's day. it isn't an early mother's day.
happy mother's day early, mother.
