Eh if you've been decent at it, just get yourself some big-ish soft wheels(something like this

I have my proper skateboard with hard wheels and a cruiser I used back when I worked in a skateshop as commuting vehicle. I still like to deny my age and hurt myself on my normal skateboard every once in a while, but just grabbing the big wheeled cruiser to go back and forth between my studio and home etc is very nice. It's both relaxing, physical exercise and gives a good feeling from just being on a board without the stress of those nice faceplants from a tiny pebble
The added clunkiness and grip of the soft wheels means you won't get tempted to try anything too crazy, it's a more comfortable ride and you can join her and just roll around, maybe drop some stuff, still do some ollies if you feel comfortable enough etc.
First time I take it out after the snow's gone I always feel like I'll break my face for sure, but at the end of the street it's always as if I've never done different.
