Most definitely, we will be there with you in spirit. When I had to put my Sami to sleep, I had to take her to the vet alone. I told my online friends that I didn't know if I could make that drive by myself and one of my friends told me to just imagine them in the car with me. That is what I did and I really felt them with me. I know it sounds silly, but I knew they were with me in spirit and we will be with you tomorrow.
Hugs to you, your husband, son, Ollie and of course, sweet, sweet Larry.
