My boyfriend warms up my car every morning now that it's freezing

It dropped below zero this week and without me asking, he started going out 10 minutes before I leave to scrape the ice and run the heater. He doesn't mention it, I just find the car toasty. Only catch: he's been using my ice scraper as a 'drumstick' at 6am and the neighbours have noticed. Green flag or red flag?
