Oh dear, lovely comments from some but I feel others take life toooo seriously and if they met would have stand up confrontation. I also think some posters could also stoop to trolling eventually. Let's face it girls/ladies/people everyone has an opinion but that doesn't mean they are wrong or right and don't need to crticise.

Sometimes it’s just the small things that press the bruise isn’t it? 😢

Occasionally he has come up the stairs and scared the s**t out of me when I have been on my own at the top of the house, we have 3 floors. Yes sometimes it gets on my wick, not enough to take the key away. Ironically, when he did live with us he lost numerous keys, but somehow has managed to retain the one he last had when he lived at home, I suppose that's why I let them keep their keys, it was their home once. Although personally, I wouldn't drop in uninvited on them, not that I have a reciprocal key for their homes or particulary want any.
