what can i beat here?

[stu-unger]

reads are that villain is an average 50nl player, so hes not very good. he is a bit loose, but i havent seen him try to make any moves. when he pushed the river i was completely lost.

50nl 6max
effecive stack ~35
dealt to hero 5 [img]/images/graemlins/spade.gif[/img]5 [img]/images/graemlins/club.gif[/img] in CO

pre flop- folded to hero who limps, SB completes, BB checks.

flop (1.5)-A [img]/images/graemlins/spade.gif[/img]J [img]/images/graemlins/diamond.gif[/img]10 [img]/images/graemlins/club.gif[/img]
SB checks, BB checks, hero checks.

turn (1.5)-5 [img]/images/graemlins/diamond.gif[/img]
SB checks, BB checks, hero bet 1.25, SB folds, BB calls.

river (4)-8 [img]/images/graemlins/spade.gif[/img]
BB pushes for ~33, hero folds...

im not sure i like the fold, but i just couldnt come up with a hand that would push this river that i could beat. ive been thinking about it for a little while and am wondering if 2 pairs does this enough to make this +EV or if its just a standard fold.
