What's the big effing deal with moving away?

Here is how all conversations now go between me and third parties:

3P: so what are you doing now with life?

me: I am moving to the UK soon for work.

3P: ORLY? When do you leave?

me: October.

3P: We should hang out.

Here is how the future will go with respect to these conversations:

1) More inquiries regarding when I am leaving

2) Ambiguous declarations regarding future social interaction

3) Half-hearted attempts at actual physical meeting

4) Apologies delivered over the Internet

5) Falsely excited hints regarding possible re-scheduling

6) I reveal I am already in the UK

Let's just get it over with:

1) We will likely not see each other

2) Luckily we will likely continue communicating thru other mediums

3) I am in fact not going on a deep space mission to Mars that requires 20 years of cryogenic sleep

4) This means we can visit or do something similar of a social nature

5) You're an idiot

I simply cannot understand people who insist on having giant attention whorish "going away parties" when they are merely leaving for 3 months or a similar stint of a negligible duration. Unless you are leaving mankind for a 10 year sojourn through the depths of the Amazon, I am not going to your stupid PITY PARTY.
