At last, my MN niche!
Jigsaws - yup, DD1 (7yo) had left a puzzle out on the roll one evening. Dh pointed out to his mother and me that if we didn't stop, we'd have finished it before she came back to it the next morning. We were just doing a little bit to help her along... (PS Puzzlerolls - ideal way to hide jigsaw...)
Countryfile/UC/OC - oh yes, Dh and I keep scores during UC and OC and crow when we win
History - am scientist by day, history freak by night. Platagenets a big fave, followed by Tudors. Am struggling with Oliver Cromwell tho'. DH and I looove castles, and regularly drag take the children to visit them, where I tell them stories about what happened, and what their life might have been like, I think my children are the only one who don't want to be princesses...
When in labour with DD3, got annoyed when I had to stop playing cards with DH so the midwife could check on me - didn't she understand I was whupping his sorry ass even when in labour.
DH has and wears a T-shirt saying 'RNA - the other nucleic acid' and was delighted when a 12-yo (roughly!) boy came up to chat to him in a playground and tell him how cool his (DH's) T-shirt was, and that he (the boy) wanted to be a scientist when he grew up.
We went fossil-hunting during our honeymoon.
Read lots of sci-fi, do puzzles (Prof Layton, anyone?). However, I am proud of it all, and don't hide it (or perhaps don't have any cool friends
)
