on yer tod...
...merrily merry...
...eating your chips and gravy...
...witnessing an argument...
...you want to step in and say "If he makes you cry on a saturday night out you should walk away"...
...but instead you lurk for a bit whilst eating your chips and then browsing DiS after finishing your chips...
...things simmer...
You decide there's only so much lurking you can do and things haven't escalated enough for you to intervene...
...just another public argument that you can do little about but acknowledge thar it'll just have to be incorporated as a (guilty?) dampener on your otherwise not bad evening...
