Tell her to join the Facebook group Ladies in their 20s/30s in Burlington! I don’t live in the area but I’m in the group and they all seem really friendly and open to meeting new people. And most importantly, tell her to go to the events! I have a similar Facebook group in my region and the people who actually go to the events, even if they’re anxious or shy, make really amazing connections and have found really tight friend groups. That and to a lesser extent bumble BFF are the reason why I have an awesome friend group as the only person under 50 in my town.
