I have invented a new word or phrase. The new word or phrase I have invented is the word or phrase status lag.
Status lag is the tendency for your IM status to lag behind reality. I generally remember to set it to “Stepped Out” when I go for a wander, but rarely remember to pop it back to “Available” when I return. Status thusly lags, in a vaguely Schrödinger’s Cat-like is-he-or-isn’t-he “Stepped Out” kind of way.
Now drink your weak lemon drink.
