New Law has passed: Your child must only have a name...

[00100001]

that is 4 letters long and begins with T

What do you chose for a boy and a girl?

Boy: Trey
Girl: Thea

Tess or Tara
Toby or Tony

Thom/Toby and Thea/Tori

smiling this is why your teachers always told you to READ the question before attempting your answer, and then READ IT AGAIN

OP I would use:

Theo (which I actually like)
Teia (which I don't like, but there are basically no nice 4-letter girls names beginning with T)

Boy: Theo
Girl: Thea

I'd steal a letter from the boy to give to the girl and have Topsy and Tim

Toby
Thea

Boy- Trip
Girl- Thai

Bloody autocorrecting fudging phone! Foiled again! I meant Tily with one L.

I'd rebel.

Tula for a girl
Taio for a boy

Boy - Theo. Girl - Teal

Thom and Tana.

Tobi for boy
Tali for a girl

This
That

Toby for a boy
Tess for a girl

Toby and Thea

Thea and Tayo

Tlbn.

Tdra

Pronounced Alban and Etheldreda, obviously.

Theo
Thea

But not as siblings!

Tara
Tags or Trey

Thom and Tess.

ALemony PMSL!

I think you'd have to go for nonsense syllables or something. Because there would be millions of Theos and Tinas running around.

Going by that theory, I reckon:

Tcio for a boy (pronounced Chee-o)
Tela for a girl (pronounced Tella)

Tilly could be spelled Tili.

Hmm or pronounced Tay-la. Now I can't decide.

Theo
Tori
