Never mind montey, worse things have happened at sea !!
You probably have already checked your rifle is still on, don't listen to others telling you to have time off, just get back out there, missing will give you the kick up the arse you need to stop taking the shot for granted that we all suffer from occasionally.
Always good to tell the truth to the landowner too as you did, like I sent a text saying there were two foxes on a stubble,I'd shot one and missed the other, which I thought was a good shot,heard no wack and watched it run up the field 50 yds or so before coming off the n/v, only to get a call the next day to say it was found dead out on the stubble further up the field😃.
And now those two will be more of a challenge for your thermal, I'd be sitting out there right now to put things right😀
