The no escaping the 'ex'

I understand that some people manage to maintain close friendships once the relationship is over. Have no trouble with that. What does set my wheels spinning is those exs who refuse to just keel over and die quietly. You know the ones who still ring up if their tyre goes flat or if they need advice on men or if they need a booty call. Any inventive ideas how to deal with and rid your life of this plague?

I've done the tyre thing, the mowing thing, the date to the wedding thing for my exs. Soft touch I guess. Nothing wrong with helping a friend out, but if it starts to intrude on your new relationship you just have to put your foot down and sever the ties.
