The criterion for including people for an all-paid Dinner Party, for instance, should at the very minimum be the people whom I can call and I am sure who will pick up the phone. This then by definition includes almost all, nah, all of my male friends and excludes most of the, if not all, ex-girls I have dated before. Then there is the proximity of location constraint. Plus, inclusion of anyone who invited me to their past celebrations and I know who maybe able to join for this one. Or somebody with whom I was close either in proximity of location or friendship or both or with whom I spent a lot of time together. Now, on top of these, in order to reduce the list to the most closest of the close current friends, I can impose the following additional requirements: 1) Should have met them atleast once this year or in the past 6 months, whichever is longest. 2) We should have had atleast one 1-1 meeting, preferably outing for >1 hour, either for lunch, coffee or dinner or something else....
