Lefty here. The only thing that I can't do with my left hand is use a mouse.

[JohntheMentor]

Add another one. And like many lefties, can also do lots of stuff with the right hand making me a left-leaning ambi. LOL.

oh hai there... INTP leftie reporting in!

[Caeci Somnia]

I'm primarily a lefty (writing and using eating utensils), but there are some things I do right-handed, like throwing, using scissors, etc.

[fantasista]

The only things I can do with my right hand are use a computer mouse and use a can-opener, both not out of choice. Stupid righties!

[A Better Tomorrow]

I'm a lefty!

[Waffleyone]

I'm definitely left handed =D. Other than using a mouse with my right hand, I might be the least ambidextrous left handed person ever. In fact, due to using a laptop, i'm actually better with a touchpad with my left hand.

[vOidwards]

I write and use my fork with my left hand, and the rest with my right.

[SyndiCat]

Right hand = Tight grips and writing.
Left hand = Advanced masseuse.

I write with my right hand, but do almost everything else (sports) with my left. but then there are sports like tennis and bowling, where I really don't think I have a strong hand, just two equally weak ones. So I'm not ambidextrous, it just depends on what I'm doing.
but I have a feeling that I am a true lefty. It took me until grade 1 to actually learn to hold writing utensils the correct way. before that, i always clutched them with a fist because they were difficult for me to control. i think i learned to write right-handed because i was either told to, or assumed i was a righty, but i really don't remember.
