I feel terrible I skipped

I had posted asking for advice on if I should go to my sisters florist appointment and ultimately decided not to go.

For those that didn’t see, my fiancé’s brother and his wife are pretty cautious about covid and passing it on to their young kids(under 5)

They are visiting for the weekend and my sister asked me to go to her floral appointment with my mom and her. After posting here I decided not to even bring it up to my fiancé because it required spending 30 minutes in the car with both of them. My moms vaccinated but my sister is not.

I spoke to my mom after who said that my sister was bummed I couldn’t make it. I feel terrible about skipping.
