O Romeo, Romeo,
wherefore art thou Romeo?
Deny thy father and refuse thy name,
Or if thou wilt not, be but sworn my love,
And I’ll no longer be a Capulet.
Can someone help me change this into a greeting card quote ?
That's a bit difficult. Greeting card verses are usually very simple. This quote from Shakespeare has a long back-story and is not a simple sentiment.
To transform this famous quote from Romeo and Juliet into a greeting card quote, you could take inspiration from its message of love and overcoming obstacles. Here's a suggestion:
"Love knows no boundaries - Romeo, Romeo,
Let us defy conventions and be free.
Cast away the chains that bind our hearts,
For together, we shall create our destiny."
Feel free to personalize or tweak the quote to suit your needs.
