beat: ex gf called me today

[whiffer1983]

when out with the crazy girl about 2 years ago. everything was crazy and i was too nice and stupid to get rid of her and ended up getting in alot of trouble and doing retarded things because of her influence. After two years of never seeing or speaking to her, i turn on my phone on my own day off from school today, and a i get a voicemail from this bitch, like "i'm so sorry for what happened, i want to give u my deepest apologies for everything that occured, hopefully u call me back so we can talk, if not i apologize." obv not the whole message but that was the important part. we went out for just under a year, i forget the exact time. . o also, we were in highschool at the time(i'm a senior now, dated end of fresh most of soph,) and at the conclusion of our relationship ( she was failing every class and was barely there so it might have happened any way) she pretty much just disappeared and never returned, which was so awesome anyway.
so bbv4life, give me an appropiate line of response
I had a few choices in mind for response but i'm sure there are better out there.
1. don't respond, its best to just avoid it
2. call and have a nice chat and be done with it
3. call and arrange a meeting and stab her upon meeting
4. call and arrange a meeting where a sniper takes her out upon meeting
5. call and arrange a meeting, beat her senseless and plant mass amount of drugs on her unconscious body, leave a fake id with the name Osama Bin laden on her and call cops and jet with the quickness,
lol
