<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">look back fondly</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for reminisce that I've seen before include "Recall past events" , "Recollect past events" , "talk about the old days" , "Give account of past" , "Talk about old times - I'm sincere (anag)" .)
