“Hot Sandwiches”I have been trying, for as long as I can remember and with limited success, to learn Spanish.My husband, Peter, says I am good, but that is because he does not speak Spanish, so if I say anything that is understood by anyone, he regards it as a minor miracle. I feel that I have been stuck at about the same level of Spanish for at least 20 years. I can ask where things are and communicate in emergencies and exchange the usual greetings, then I dry up.

Then I realize that I’m not even sure that I do especially like hot sandwiches. And even if I did, who would care?The next phrase is waiting for me. I move on.“My dog never takes a shower.”Well, I no longer have a dog, so this phrase appears to be of even less use. It is true, when I had a dog, he never took a shower. Was he supposed to, I wonder? Would someone ever ask me this, in Mexico or anywhere else? Under what circumstances would someone ask, “Say, how often does your dog shower?”“Oh,” I’d confidently reply, “My dog never takes a shower!”Again, I’m coming up ...
