Ooh I love these, haven't RTFT just yet but let's see how many of mine i can remember:
The oddest one, sometime when I was in secondary school I realised it had been over a year since I had spoken to my childhood best friend and my mum suggested doing something with her. I rang her up but it was engaged. Rang back a bit later and she said how weird it was that I was calling as she'd tried calling me that day but it was engaged: we'd both tried to phone each other for the first time in ages, on the exact same day, at the exact same time.
My ex and I met in college, it was only months later we worked out that his mum ran the after school club I used to go to and although he was from a different school, she would bring him with her- we had probably played together at some point as kids!
I had extensions on my wedding, and decided to have them taken out about 4 months later and have my hair cut quite a bit shorter. Around the same time my mum was shopping where she lives, miles away, and had the sudden urge to get her hair cut(she always prebooks hair appointments). She rang me when she saw my shorter hair on facebook as she was very surprised at the coincidence. Same sort of thing with my dad, when I lived at home there were two occasions when I had a song in my head all day which I hadn't listened to, which turned out to be what my dad had been listening to on the way to work.
A more recent one- me and DH are gamers and I used to work in a game shop so had many years of free xbox live membership stacked up which we share. I knew it was expiring some time this summer, not a big deal as we are expecting a baby and doubt we'll have time to play. Went to check exactly when it runs out- it's our DD's due date!
DH's sister has the same birthday as his dad.
This is only a maybe, but I'm pretty sure we saw a couple last holiday, that were on our previous holiday (following year, different month and location), but as I have some degree of face blindness it probably wasn't them!
My parents have relatives who are married without having met through them.
I also get followed by the numbers 58 and 13 (which is also 5+8)!
I don't believe in anything woo but that makes these things all the more fascinating for me!
