This is a rerun episode of the "Advice Session" podcast where Emma answers listener questions about crushes. The podcast covers three main areas: determining if a crush reciprocates feelings, knowing when to give up on a crush, and navigating casual hookups without developing feelings. Emma advises against reading into subtle behaviors and suggests directly asking around or building open communication to determine if a crush is mutual. She emphasizes that letting go of a crush requires patience and potentially creating distance, and that casual hookups are easier with someone you're not strongly attracted to, but acknowledges this can be difficult for those who view sex as more meaningful.
