Much like others have already stated, might as well leave the calendar at home, preferably in a place where the in-laws or someone else outside of your gambling circle won't see it.......it will only be a conversation starter for something you don't want to talk to someone else about.....if you want a conversation starter you might as well leave a mirror on the coffee table with a razor blade on top of it.
I got a hat and a shirt but if I wear them all that's going to happen is someone's going to ask about the source and then you're firmly going down a road you don't want to travel because of the stigma attached to gambling......doesn't matter if you win at gambling or not or whether you're middling or scalping books to death, anyone outside of the gambling world will not understand the math or low risk involved in arbitrage and just consider that you have some sort of problem regardless whatever level of control you maintain.
Someone else mentioned about taking it to work and maybe five friends will sign up and you'll get referral bonuses......nah, you'll just be thought of or branded as some out of control degenerate.......I have numerous friends that have gambled for decades, and out of that group I've only been able to convince two of my friends to go offshore, the rest of them seem perfectly pleased to get bent over by their local getting a line four days after it comes out with all the value beat out of it......I could write a book on the disadvantages of staying local while the upside only would contain a brief footnote. But that's another topic. I just listen to them b1tch about not getting a bet in because their man was gone, b1tch about bad lines or disputes or not getting paid, circled games and totals they can't bet because their out is too chickensh1t to hang complete numbers......skip the sales pitch, they're on their own......if they want to set up an offshore account they can bug me for it, when/if they choose to do so then I'll know they're more serious about trying to make a profit and I'll clue them in.....until then they can flop like a fish on the beach.
