I really really detest being split up.
At our wedding we had designated tables which we divided according to freindship groups. I mean- people are paying money to come and be with you, the least you can do it make it so they are with people they either like (which you know already) or they may get on with.., which you have to guess.
My Dh and i barely get out just us nowadays. It is a pretty big effort when we do, with babysitters and no family about. Added to that, i am very shy, and gain confidence when next to him. So i am better with him beside my side.
Last August we went to the biggest event of the year for us. It is a major cocktail party-come dinner- come 'breakfast' so is from 6 pm to about 2 am. It is really the only thing we go to nowadays. So, babysitter at 7 pounds per hour before midnight and 11 pounds after. £95 per head for the event, without alcohol. Taxis for us, and the baby sitter to get her home safely. New dress not for several years now and then alcohol on top of that.
All i wanted was to have a nice night out. i was seated next to a fat, red faced sweaty bastard who has a history of hitting on me, and who kept breathing beer fumes over me, putting his hand on my knee and asking me if sex with my husband was worth it.
I bailed out at 11 as i could not bear it. DH was seated next to fat sweaty bastard;s wife who kept giving me evils.
fucking horrid evening. And we paid all that money for it. Okay, so it is not a wedding, which is where the Op came from, but the pricniple is the same. you want to wish your friends well and have a nice time- which may have been quite difficult to arrange, pay for and organise. At least you can sit next to someone you like?
