Re: If..
I guess it would depend on the complete circumstances.
Why were they upset with you? What exactly did they do to you while they were upset?
How good is your friendship. How hurt exactly were you? Is the friendship worth the heartache they caused? Or was the heartache worse?
It's not really a matter of the flowers. The flowers are just a way to initiate a resolution. The question really is; are you ready to let things go and 'make-up' with your friend?
