안승규의 블로그 (Stay hungry, stay foolish)

I just want him to fit it in.

Living in Sedona has been transformational.

I convinced dad and gloria to invite her.

Somebody's full of herself.

Why are you always on me about everything?

Guys pull pranks like that all the time.

Instead of drudging up the whole incident,

Maybe you could pave the way so that I can apologize.

You're reaching out, trying to hold on to something awesome.

They kept patting my butt.

I was gonna get it.

I was just being facetious.

I'm pretty sure this is a typo.

He is a snob.

I'm discerning.

I was a hick.

He's a little jumpy.

I'm all about taking it to the next level.

It's not really her thing.

Your thing is to provoke.

Every time I would get a little boisterous,

That's no way to talk to your grandmother.

It's just kind of irritating.

I think I strained something.

She just moved in down the block.

We'll have to have you over sometime.

I worry about the ridicule he might get from loudmouth bully.

Sometimes a man's gotta put his foot down and do what a man's gotta do.

Kidding. Just chill, please.

We're gonna start with the hello dance, and then we're gonna move on to blocks and finger painting.

Any chance I could get a break on this one?

Just get me to wine country.

You think I like this arrangement?

Why are you trying to sneak around and hide things from me?

Let's take it down a notch.

I'm having a friend over today.

I might as well just tell him not to come.

I'm bound to be a little surprised,

I didn't mean to.

Now you have to follow through.

What the hell is that suppose to mean?

It's supposed to be nothing.

Don't answer it, I'll get it.

She is like completely freaking out and embarassing me.
