Anyone else feel less social when with family in public?

I’m in my late 20’s and still take family vacations with my Mom and Dad from time to time. I noticed that when I’m with my family I feel less like myself in social settings with strangers (less outgoing, charismatic). If I was by myself or friends I would be more likely to smile or chat up the stranger standing in close proximity, or if we’re at a restaurant I feel like they direct more of the attention from the staff. Anyone else feel like this? Any tips?
