I am definitely not doing cheap-ass June, it is my 40th birthday and I am splashing the fuck out. ;-)
May went a bit overbudget mostly because of gifts and donations, which I can't make myself feel THAT bad about. $25 to help a slight acquaintance with medical expenses after they were randomly robbed/attacked on the street. $25 to help a friend start up a kids' theater non-profit org. $125 on Mother's Day stuff including gift, card, chocolates and train tix. $85 for a surprise birthday gift for some close friends (gifts, chocolates, cards, int'l postage). I don't usually exchange significant gifts with friends, but it was a major milestone birthday and the person in question is in massive need of a pick-me-up after the truly difficult year they've had (major illness, job loss, etc.). More than happy to deduct that out of my savings rate.
Other than that the only really questionable purchase I made was an expensive concert ticket, but I am going to budget that retroactively out of birthday money.
In spite of going overbudget, it was a great savings month because I finally got access to a 401(k) and can save so much pre-tax! I'm having a hard time getting used to locking up all my savings, though. It used to be I'd have ~$500 a month pre-tax into the IRA and then the rest taxable, which is all easily accessible to me. Now I'm not putting anything into taxable savings, so if I go over budget, that comes out of existing savings instead of reducing the money going into savings. It's silly to be anxious about $100 when I have $55k accessible in taxable accounts, and money being fungible, but... I am. :-/
