Not everyone's brain works the same way. For people with ADHD (and other neurodivergent conditions), executive dysfunction can make it really hard to remember to reach out -- even to people they care about deeply. It's not about not valuing the friendship; it's about how memory and motivation work differently.
Instead of disparaging people for using tools that help them maintain relationships, maybe try having a little empathy -- or at the very least, an open mind. Not everyone connects the way you do, and that doesn't make their friendships any less real.
