How do you say sorry in different way?

I apologize.

or:

Forgive me. if you want to say sorry in a different way try giving hints to that person if they wont talk to you, say your in school and you try to say sorry to that person but they wont listen to you try this: 1.sorry. 2.are we still talking to each other? 3. I was kinda hoping we could still be friends. 4. I miss talking to you. 5.do you still have my phone #? 6.or write that person a note and have someone else give it to that person.
