I wonder if other Gemini Mercs when younger are like my daughter in that they are very expressive with their bodies - hands gesturing thoughts, faces contorting to match emotions and such. I can sometimes pick up on her moods merely by the pace of her stride.
Witty and appreciative of wit is, I think, another good fit I'd attribute to her Merc.
Hers can be intense and nigh impossible to hide:
I love it when she comes home from school, almost hyperventilating from the excitement of wanting to share something that happened during the day 
I think so, Matthew! It's up on the top of her chart....she can't help but express it so openly! She sounds like her excitement can be infectious
My dad has this placement. It's square his Saturn, Moon, and Jupiter, and trine his Neptune. He's extremely, extremely smart; supposedly my intelligence comes from him. He and I both have well-placed Mercuries as mine is in Virgo. I think the difference between us is he is more of a gatherer of facts and information, and has a wider set of interests, whereas I am more analytical.
Great observation, Magic! Thanks!

Certainly Today it was to let me know she wore my Nirvana shirt to school today - yay, she actually told me before I found out on my own this time... ha!
I've long ago infected her w/ my snark (I didn't know then she had so much Gemini, I swear! a snarky lil' Gem, I know, what have I done, right?) I had to ask her though, "So, did you get any compliments on my shirt, today?"
*chuckle* "Yeah, a couple girls said 'Dad goals' when I told 'em it was yours."
"Dad goals?" WTF?!? <- that part was on my face.
So she explains to me, "Like, when ya know, someone sees some shoes they really want..."
'"Oh, so 'shoe goals' then?"
"Yy...yeah..."
Aww... <- that part I saved face
@Matthew, that exchange you shared, I laughed out loud. Witty and snarky! 
Quick-witted Gems!
