Somewhat a delayed response from me, not been on here properly for awhile!
Highs:
Transcend went from strength to strength last year, as did Dark Matter.
Work has been great recently, settled in to my new role over the last 12 months. Been with my company 8 years now, it's mad.
Lots of good events, and festivals.
Trip to Ibiza. Fell in love with the island again this year, as we spent much more time exploring it. Very happy with that.
Haven't killed my girlfriend since she moved in, so that's good!

Planned a stag do and it went really well, stag loved it.
Lows:
Moving out of our house in Wandsworth. Group of 8 of us have gone our separate ways. Will miss that house, as it was huge.
Brexit is making things ever more expensive. I think we're in for an interesting couple of months, but it could be disastrous if we leave with no deal by default.
