I think "never say never" is so true - and also that you will know what is best for you. Yes, you are free to visit e.g. GC without a dog (unless they are doggy people) but it is also true that a dog will get you out even on miserable days and if you are alone, there are always other dog walkers to talk to! I often think a dog is an excellent "chat up" accessory - not that I have ever availed myself of it!
After 16 years of a wonderful black lab who grew up with our children, I was devastated when she went and the next morning read about retired racing greyhounds - it was as if someone somewhere was telling me something. We have had 3 greyhounds - 1 dog and 2 bitches - they are lovely affectionate and gentle dogs, need VERY LITTLE exercise - but you do get lots of street cred from people who think you run a half marathon with them every day.They rarely bark, are not destructive and can actually cope with being alone as long as they have a comfy bed (although they prefer sofas, but you can be firm, if you want) As they are retired as young as 4 you get a reasonably young adult dog for perhaps 6-8 years, usually housetrained with few underlying health problems e.g.from inbreeding. They don't need a massive amount of food either, ours has a standard tin of woof plus mixer but of course given their size you do have to keep food out of their reach! And they are so appreciative and loving! End of comercial! Will I get another when the present girl goes? I will know when that sad day comes, but I do wish my parents had got another easy little dog in their latter years it would have kept them mobile.
