breaking up

What's the best/worst way to break up with someone you're dating, not all that seriously. A purely academic question. In order of options available there are, in person; phone; fax; text message; email.

Is email so bad these days? It gives you privacy to get the message and also allows the person on the receiving end to get on the moral high ground and really hate the person that broke up wiht them. For the person sending the email, they don't have to be there in person, they can do it from work, they can go on with their day. They should of course turn off their phone at that point. It should be written with care. One has to assume it'll be forwarded to all their friends. Perhaps sent to a newspaper or something. So caution is advised.

Texting seems quite bad too. Perhaps worse. At least in an email there's room to be a little expansive, or explanatory. Texting using short hand iwould be bad. "u r g8's" or something like that. I think out of respect one should at least have predictive texting switched on. Please let me know your suggestions for texting a break-up.
