some kinda of a hunch or feeling. doing stuff that are not the typical lesbian. words, actions, activities. personally speaking, Elise acts more like an exhibitionist than showing her sexual orientation or preference. for me, Elise in particular behaves more feminine than your typical lesbian. for example, my wife is a tomboy and behaves more manly than her feminine side. even behaves more manly than Elise. can't force the woman into pole dancing but pretty much liked the idea of doing martial arts and boxing. wife could easily pass the profile of a bi-sexual as she likes women also, my type of women. and she likes men as well and as much as women. not saying I'm an expert on distinguishing people's preference but typically notice some behavioral cues that seem to fit the profile.
while it could be true that behavior can change over time as well as preference.
