Mental block and model block

ok I haven't taken pictures for a while... want to do set up shots like the CSI rather than the naturally occurring ones but having model trouble... bit of a mental block atm. wanted someone to go run in the rain for me today but no willing people at hand. feeling guilty I'm not going home for mothers day. My boss even offered to pay for my train ticket home if I'd work the sunday.. he loves me ! I think its my essay. Its making my head melt. Talking of which may do some ice shots... need an ice cube tray tho. will hunt in town tomorrow... how does it take for it to freeze?thats how long my pics will be...
