Not mean at all.
We didnt have a tree last year and we're probably not going to have one this year either. We have no room for one, and Ollie would do himself, the tree and MJ damage if there was one up.
We did have the windows decorated so we looked a little festive, but there are plenty of years for them to have the whole house decorated.
TBH our neighbours are putting me off doing anything this year. They put theirs up yesterday and they have literally covered the garden, walls and roof with really tacky looking decs, and there's a tree in every window. IT just looks way too much and really tacky. I dont mind a few tasteful lights outside - some displays look really good, but I'm afraid this one doesnt, its all odds and ends that they've just flung up in no pattern/order...
(The house behind us usually does something equally as tacky and theirs is enough to light up the whole street!
