Not counting errors from receiving texts from friends and relatives who selected the wrong person in their contacts. Talking texts from people you never contacted before. I can think of two recently. One was a primary school in Brighton texting to say the balance for the residential is due on (date). The other one was texted today from a owner of some holiday cottages near Swanage about she found a necklace in the communal car park and asking who does it belong to. Both instances I googled the name of the school and holiday cottages to be nosy!
