You Know You've Been Playing Too Long When …

.....when you see a sim come walking in the distance, you recognize them by the hair and clothes from 2 miles away, and you say to YOUR sim: "Hey that's XXXX, haven't seen them in a while. Lets go say hello!"

I talk to sims often, greet them when we (my sim and I) are out and about. I give them pieces of my mind too, if they're being dumb.
