Truths and roses have thorns about them.

If you don't feel the pointed things in life, you'll soon take the soft ones for granted.

I'd rather let you cover all my roads with thorns than with dead roses.

But he who dares not grasp the thorn
Should never crave the rose.

Roses fall, but the thorns remain.

Life is like a bed of roses, so much is beautiful, but be mindful of the thorns.
