True, but Sense Motive (http://www.d20srd.org/srd/skills/senseMotive.htm) can be used for more than just seeing past lies.<br/><br/><div class="quoteheader"><div class="topslice_quote">Quote</div></div><blockquote class="bbc_standard_quote">A successful check lets you avoid being bluffed. <strong>You can also use this skill to determine when “something is up” (that is, something odd is going on)</strong> or to assess someone’s trustworthiness.</blockquote><div class="quotefooter"><div class="botslice_quote"></div></div><br/>Although, even in the alternate uses described above, I think it would still be opposed by a Bluff check, hence my giving you the chance to make one... ^^;
