"Let me think about it"
Here are a few rules if you do decide to defer:
- Only one defer allowed per person. Think of it as a rare coupon you don't want to squander.
- Make your decision time bound: Limit how much you're willing to spend on it, and don't make it too big - one hour max, say.
- Commit to a decision by a specific date (no longer than a week), and tell it to them. Then keep your word.
"Let's get together sometime"
Pick a date.
"Interesting"
This is a true classic, and often means "That's really uninteresting" and/or "I disagree but don't want to get into it with you." To be fair, this can also mean "I don't understand or agree, but I'm willing to think about it." Also, it rally depends on the tone.
