Take care

I don’t know why but nowadays every body seems to say this all the time.  My problem is that I overthink things now so whenever someone says it it makes me think about why they say it.  The people who say it to me are really nice and of course it is a nice thing to say but it doesn’t seem real to me.  Probably as I don’t really know what it means.  Why not just say goodbye?  How do you get into saying it in the first place?  My estate agent said it to me today and that was really weird.  I need to ask Michael McIntyre to talk about it on his show, that would really make me laugh!
