A5s, TPNK, fold to a raise?

[House-Lion]

Where did I go wrong here? Fold pre-flop?

Table wasnt aggressive.

Pre-flop: Depends on the table, you want a really loose/passive table to open here with A5s.

Flop: Depends on your read of the SB. He didn't show any aggression pre-flop reducing the chances of being up against AK/AQ. Would be a really silly way to play a flush too. With a small pot, you can fold here if you think he's got a legit check/raise hand.

Do you mean call the raise and then fold on the turn unimproved or just fold to the raise? I hate to fold to raises since people may quickly start taking shots at you.

Either line is fine. If they want to take shots at me, so be it.
