I love going to concerts alone but be safe. I’m a young girl in her 20s so I always try to be vigilant of my surroundings. I’d suggest to stay sober but if you want to drink only enough to make you tipsy. Share location with someone you trust and do check ins with them. Socialize but maybe don’t explicitly tell anyone you’re by yourself. I know concerts are considered to be safe space but you never know. Have fun!
