Well, As far as the interaction between BM and I, It went fine. We got along and we both had an ok time. As far as BM and her hosting ability... that is another story. Here is a list of things that she did that I couldn't help but shake my head at:

Cut the cake while SS was playing out back. No bday candles, no "happy birthday", and SS didn't even get a piece of cake because it was gone before any of us even knew it was being cut

Didn't want anything to do with SS... yelled at him for "Bugging" her while she was talking to her friends

Got hammered. Couldn't even walk an hour before we left.

Went from door to door around her neighborhood looking for vodka... and even came back with a bottle of vodka and a bottle of soco.

SS begged to spend the night there because it was getting late, and he wanted to play with his new toys. BM told him that he couldn't stay because she had to be up early tomorrow. BM's BF said he could stay and that it was no big deal if she had to leave 15 minutes earlier... she threw a fit because she would have to leave at 7:45, so BM's BF stepped up and told us that he could stay the night and he would watch him tonight and then bring him in the morning on his way to work at 5am.

BM was so hammered by the end that she was hanging all over my BF, me, BF's family, and kept grabbing for BD even though she could barely walk

So in the end... SS was heartbroken because he was told he couldn't stay there and BM was too drunk to even care. He was at our house sat of last week until friday at 630 and then we had him from 10-7 yesterday... he misses his mom and hasn't seen her in almost a week and she could care less. She just didn't want to take care of him. SO and BM's BF figured it out so that SS could stay there with him tonight and he would drop him off in the morning. HE should not have to pick up the slack for lazy drunk BM. Not to mention the fact that I don't think she should never have gotten drunk at a 5 year old bday. If you cant just have one... dont have any! Last year she slept for his whole bday party because "her meds made her sick" this year she is so hammered she will never remember it. I feel so bad for SS. He can be such a sweet heart. BM is bringing out the worst in him and is really showing him an example I never want him to see.
