It's all about expectations and state of mind. I enjoy one night stands, but there may have been a few occasions where a bit of drama or heartache ensued due to either wrong expectations or bad self-assessment (the latter also on my part, I admit). It's easy to fall for someone fast if the sex is good. OTOH, I've had a few which still put an instant smile on my lips after 30 years. The hard lesson I thankfully learned: it's either get sloshed or have a one night stand. Both together tend to end in a lot more headache than the alcohol itself already causes. But reasonably sober: hell, yeah!
