Yet ANOTHER Expression I Hate....

...when people take the pronoun out of a reply. For example - something I heard today:

"Appreciate it."

It made me wish I hadn't held the door for her.

Where's the I? I feel like people take the pronoun out to sound more professional or savvy or fast-paced (I don't have time for all the words that belong in this sentence!). Ugh.

In googling the subject, I found this line I couldn't agree with more: pronouns are like condoms, always use one. Thank you. Thank you very much.
