S/O doesn’t understand

I have my sisters bachelorette in a few weeks. I really want to be vaccinated or atleast have my first shot before I go. I’m officially eligible the 19th if I can find a shot, but no guarantees because it’s when it’s open to all ages. The bachelorette is April 29th.

I found a vaccination site an hour away that has a waitlist setup and they’ll call you if they have extra doses or ones about to expire ect.

I tell my S/O I’m getting on the list and he’s like “why not just wait, we’re eligible the 19th it’s a week away” then told me I can do whatever l want and started checking how far it was for us to go.

I’m worried that if I wait the week or so It’ll be extremely hard to get an appointment and then I won’t get one before the trip.
