Casual dating typically involves getting to know someone in a more relaxed setting, spending time together, and potentially developing a deeper connection over time. On the other hand, hooking up usually implies a more physical and immediate encounter without necessarily the intention of forming a long-term commitment. Ultimately, the choice between casual dating and hooking up depends on individual preferences and what one is looking for in a relationship. It's important to communicate openly and honestly with potential partners to ensure both parties are on the same page.
