Possibly 

Gowan gowan gowan.

Sorry can’t, will be at an awards ceremony

sadly haven’t even been nominated for one

Awwww.  Not even Sexpot of the Year?

The national librarian boobie awards.

They've stopped doing that one because she kept winning.

*BUMP*

Afraid I have a prior commitment.

what's happening on friday? 

Nothing, Friday just won't be as sunny.  Plus all the pubs will be choked with corporate w**ker types on a Friday.  No need to add to their number, eh?

heh @ a lawyer distinguishing himself 

I will be in Londres on Friday ...hence

but still a swift pint on friday might not be a bad thought

Not distinguishing myself ay all.  Re-read last sentence.  Ah well , maybe this will gain more traction tomorrow.  Otherwise I'll just go and have a drink with Stix (which is never a bad idea).

Sorry dude, no can do. 

?

badders mate ...I was pulling your leg. Try to be available on friday also, if you can. been awhile since we last met

I’m going to ignore the usual attempts at hijacking and derailing - presumably we are still on for this evening?

Well?

Hi Stix,

Sorry, lovely, but I'm going to have to cancel.  Screwed with work and a lot going on with the house move at the moment.  Should be clearer by Friday, if you're still up for it?

Sorry for being impossibly useless.

No, I’m not around on Friday I’m afraid.

You are forgiven.

Thank you (and grovelling apologies again). 

This went well

Rearrange this sentence:

Off fook aunt boring you.

To be fair, he has a point 

He does.  But he's still a coring bunt.
