This brought back a memory for me. We were at a parent teacher conference for my oldest when he was in early elementary school and the teacher asked us what we did for vacations. We relayed a few to her, then asked what brought up the question. Apparently another young lad in her class told everyone he went “on a trip/vacation” to Grandma’s house for a weekend day and my son “corrected” him saying, “That’s not a vacation! In order for a trip to be a vacation it has to have at least one night away from home and not with relatives…” It seems he was rather adamant about it all.
Not once did we define a trip/vacation to him in that way - he developed that definition completely on his own - but that night we did have a conversation about “different stroke for different folks.” One never knows what one needs to cover when raising kids!
