I came to last week's one, so I'm barred from this.
Tho I feel I should go along and make John feel better because then he wont be the oldest.
I can recommend sending John an "are you there" text message from an unknown number as a way to spot him at the bar. Either that or look for the table with a disproportionate amount if Guiness drinkers.
I have decided (for now at least) that I will be going despite fears of complete social awkwardness.
Get the 149 bus. Landmarks, anyone? I can never remember what's south and what's north in relation to there, but if you see Nandos on the right, you've gone slightly too far.
If you get really nervous, just use another Dissensus user's name. Go through the member list and find someone who hasn't posted for a while. Then, if you bottle it, everyone will think that it's THAT person who's deeply social awkward, not you.
