Take for granted? No...but I think we accommodate to our surroundings and probably don't appreciate what we have as much as we should!
The advantage of a sea view is that it's never the same, so I don't think you would ever get used to it. Oh, and Happy Birthday to your husband! A significant milestone indeed (although still seems young to us...)
I hope that I wouldn't ever take it for granted although I'm sure I wouldn't have time to look at it all day long. Thanks for the birthday wishes, Pam.
