I bet.
I blew it.
I can live with that.
I can’t complain.
I can’t say fot sure.
I couldn’t care less.
I didn’t get the memo.
I don’t have a clue.
I don’t kiss and tell.
I don’t know.
I got it.
I got pissed off.
I have a headache.
I have a sweet tooth.
I have my moments.
I have stiff shoulders.
I heard it through the grapevine.
I hope you like it.
I just work here.
I knew it!
I like you just the way you are.
I mean it.
I need it ASAP.
I owe you one.
I plead the fifth.
I rest my case.
I see your point.
I slept like a log.
I spoke out of turn.
I told you.
I wasn’t born yesterday.
I went too far.
I wish I could.
I wouldn’t bet on it.
I’d appreciate it.
I’d like to ask you out.
I’d like to return this.
I’d rather not.
I’d rather not say.
If the shoe fits, wear it.
If you insist.
If you say so.
I’ll be damned.
I’ll cross my fingers for you.
I’ll do my best.
I’ll get back to you.
I’ll get even.
I’ll get it.
I’ll get right on it.
I’ll give it a try.
I’ll give you that.
I’ll have the same.
I’ll have the usual.
I’ll have to beg off.
I’ll keep that in mind.
I’ll never hear the end of it.
I’ll pass.
I’ll say.
I’ll take a rain check.
I’ll take you up on that.
I’ll tell you what.
I’m afraid so.
I’m all ears.
I’m available.
I’m beat.
I’m broke.
I’m done.
I’m easy.
I’m flattered.
I’m game!
I’m home.
I’m in the dark.
I’m in the middle of something.
I’m lost.
I’m mad about you.
I’m not in the mood.
I’m off.
I’m on my way.
I’m on the wagon.
I’m on your side.
I’m through with you.
I’m working on it.
Imagine that!
In your dreams.
Is that a crime?
Is this seat taken?
It can’t be helped.
It happens.
It makes no difference to me.
It means a lot to me.
It never hurts to ask.
It takes one to know one.
It takes two to tango.
It’s a deal.
It’s a long story.
It’s getting out of hand.
It’s none of your business.
It’s not my cup of tea.
It’s not my day.
It’s not rocket science.
It’s now or never.
It’s on me.
It’s over my head.
It’s the least I can do.
It’s too good to be true.
It’s up to you.
It’s water under the bridge.
It’s your call.
I’ve been expecting you.
I’ve been tied up.
I’ve had it.
I’ve seen better.
