I recently ran into a friend I hadn't seen for a long while.  Our conversation was lively andfull of news from both sides.  Before we parted she said  "You'll have to drop in sometime. "immediately  sensed that if I  simply  " dropped in"  I would take my friend by  surprise, and  I would be discouraged by the image of her standing in her doorway, staring at me, and asking, " Oh ,err …what brings you here?"

Whatever happened to the unannounced drop-in visit? When I was growing up in the 1960s, it seemed that people-mostly relatives,  but also friends-were always dropping in .  My parents would put coffee on, and my mom would find something in the kitchen to serve along with it. Then the conversation would begin…The neighbor lady, a worrier, was unloading her sadness while my mom quietly listened. The Irish man next door had such an atcent that I remember asking what language he spoke. My Polish relatives arrived in packs…But I never heard my parents say any- thing like  " We  weren't expecting you"  or  " This  isn't a good  time.  " Drop-in  visitors  had  a certain right of way and became No. 1.

What happened to such visits? Actually I know the answer. Times have changed. Everybody gets busy with work. There is no longer a stay-at-home mom keeping a pot of hot coffee or tea ready throughout the day for a surprise guest. Exploding malls and stores are now replacing homes as a central form of entertainment.

Just the other day a former student of mine showed up.  "I'm sorry for the surprise visit. " my student began.  "I just wanted to see if you still lived here.  I'll only stay a minute. "

My response was immediate.  "No, you won't," I said.  " Just come in, sit, have coffee, and we'11 talk. "I had nothing in the kitchen but we ordered pizza.  And we had a lovely time.  I have tried to keep the drop-in tradition alive though it takes some effort.
