I am game a-z

[kitten]

I am yielding to my need for sleep.  Did your X stand for x-cellent?

[P.C.]

I am zipping through this section.  I too am ready for some ZZZZZZZ's

[purelife]

I am about to head for bed soon....am tired...  

[Sportsdude]

I am 'bout to go to work in an hour.  

[Russ]

I am confused by some of these answers

[Gopher]

I am dazed by their  manifold brilliance  

[kitten]

I am envious of your witty repartee.

[Gopher]

I am free from all trace of artifice

[kitten]

I am going to be convinced one of these days.

[Gopher]

I am holding my own

[kitten]

I am intrigued to know if it hurts when you do that.

[Gopher]

I am judiiciously telling you that it's the only time I'm entirely painfree this week

[kitten]

I am keeping my fingers crossed for you.

[Gopher]

I am levitating my hopes that they'll do the trick

[kitten]

I am mesmerized by your charm.
