Firewall
Friendships
The Friend Who Notices First
A Firewall is often the one who says "wait, don't do that" before anyone else has even spotted the risk. Friends learn to trust that radar, even when they don't fully understand it in the moment.
Lending and Owing
Where some types lend freely and lose track, a Firewall tends to be precise — they remember exactly what's owed and to whom. This can read as stinginess to a friend who doesn't think in those terms. It's not distrust. It's just how the instinct is built: precision, not generosity accounting.
Group Money Moments
In a group setting, a Firewall is the one who catches the split that's off by a few dollars, double-checks the bill, quietly protects the group's money even when nobody asked them to.
What Friends Need to Know
The checking isn't judgment. It's not a comment on anyone's character — it's just how a Firewall is wired. Friends do better inviting the radar in early than resenting it after the fact.
