1. Borrowing each other's stuff without asking.
If I had a dollar for every time I'd gone in my case to find my tuner, lead, 9 volt, spare string, whatever..... only to find it missing or not how I left it, I would be very rich indeed. But, I give as good as I get and at present, only 75% of the strings on my guitar were paid for with my money. So, that one balances itself out!
2. Knowing where each other is, every day of the week!
Keeping track of each other has it's merits; it's hard to book a gig if you don't know if everyone's available and that expensive rehearsal room won't be free just because you left it to sit empty for a week. Having to put in for your three day trip to visit your family home six months in advance is pushing though - so watch out for control freaks!
3. You have "mutual friends".
If your band gigs regularly, chances are you'll meet each others friends. Meet them often enough and they'll become yours too. I recently went through my Facebook friends list to send out invites to a gig, and discovered to my horror that I knew less than twenty people in my area who weren't mutual friends of "Insert Band Name Here".
Those twenty event invites went a long way to getting the numbers up at our gig - NOT!!!
4. Arguments about money.
The music industry is an industry and it requires an input of cash from somewhere. Whenever it requires a cash injection from you; be it expensive studio fees, band merchandising costs, or top quality CD pressings, try not to argue about it! Like a relationship, it only slows things down and wastes energy.
Unlike a relationship, the making up afterwards is nowhere near as good!
5. Spending way too much time together.
When a group of creative types work well together, it can be hard to switch off and tune out for a while. In my current situation, musical matters get discussed nearly everyday. There's trips to the pub to check out other bands, weekly rehearsals, gigs at least once a week, piling into each others living rooms for an emergency song writing session......a night off just doesn't seem to exist. But if your band are buddies, being in constant demand can be one of the best things! Just watch out if your significant other asks you flat out if you're still in a relationship and feels the needs to add "with just the two of us?"
6. Meeting the family.
When your band gets to the level where it needs the kind of time commitment a full-time job would, it's only natural your paths will cross with each other's families. This is also a big plus in my book; especially if you're a mixed gender band. Some of my band buddies Mrs's are my best friends and all those late nights and absent weekends won't raise any suspicious eyebrows if partners are kept in the mix.
7. Moving in together - sort of.
If things start to hot up with your musical act, it's only a matter of time until you have to expand your horizons and play gigs outside of your home town. When this happens, you may find yourself sharing a car, a hotel room, or even a tour bus with them. It's these times in the lifespan of a band when you discover just how small a drummers bladder can really be, and wonder whether or not you should just stick your finger up there yourself to see how inflamed that prostate is really getting.
8. Celebrating significant life events together.
Just like that scene from Guns N' Roses "November Rain", you may find yourself tearing up at the sight of one of your bandies getting married. This has happened to me twice and has been the only two moments in my life when it's been remotely acceptable for me to compare myself to Slash.
For better or worse, for richer or poorer, being in a band is one of life's most awesome adventures and I wouldn't change it for the world!
