What to say when they don't accept your first "No":
But it'll only take 5 minutes!
""I appreciate that, but I'm protecting my time right now and can't take on anything extra, even quick tasks.""
Everyone else is doing it...
"That's great for them! I'm sitting this one out, but I hope it goes well."
I thought we were friends?
""We absolutely are, which is why I'm being honest with you instead of saying yes and resenting it later.""
The Guilt Trip: "After all I've done for you..."
""I really value our relationship, and I'm grateful for your support. This particular thing doesn't work for me right now.""
