A little bit of background. The twins (B/G) are in year 12 at school, like many twins they were very close when they were little and all the hormonal chaos of puberty didn't change that. They had their moments, what children do not, but I think DH and I have been lucky.
The problem, if problem it is, is that sometimes I think they are too close and by now they should be doing more things on their own. There are doing the same AS subjects, fair enough there were also their best subjects, but they seem to assume they will also go to the same university.
Over the last year I have noticed a few things, perhaps insignificant on their own, but when put together worry me.
Yesterday was one. They came home from school and straight away went upstairs to change out of their "smart business attire 6th form dress code" clothes and into the usual jeans. Nothing unusual except I know for a fact that DS was in DD's room while she was getting changed. They were chatting away about a mutual friend, nothing furtive, but it seemed very strange to me. They do sometimes appear a bit like boyfriend and girlfriend rather than siblings. DH (whose user name I have borrowed) thinks it is 100% OK but I do worry a bit.
