It goes like this at our house- Brutus learns from my husband. He basically ignores most everything I say, except for, "what's your problem?."
I don't know if he looks at Larry as the competition for my affections, and so wants to talk just like him or what. Anyway, my husband is an airline pilot and is gone several days a month. When he gets home, Brutus becomes his alter-ego, "the recorder." Larry will pick him up and you have never seen such rapt attention in your life! At these times you can almost see the wheels turning in his head as Brutus is trying to record every word out of my husband's mouth. Sometimes when Larry is in his office and conversing, Brutus will pick up the rhythms and just mumble a bunch of stuff, like HE'S having a conversation. Funny!
And then, when Larry is gone Brutus will practice and perfect (or not) what he has taken in. In case we ever lost him, we thought it would be a good idea if Brutus learned our address. So far it is just, "four, zero, zero, zero", maybe we should move to a 4000 number address?
