Mother in law

Just venting my anger. My LO’s one year old birthday, we ordered specially designed cake to celebrate on his actual day. Ended up, just because my BIL didn’t wanna come over to celebrate, his whole family didn’t turn up. We have to cut the cake just me n my hubby n baby. Luckily I didn’t order any food (some women’s instinct). I will not arrange anymore birthdays. What a lousy MIL I have. She grumbles all the time, why didn’t I bring baby to her place every week, when she doesn’t even play with baby. Her hse is full of cigarettes smell + dust (hoarder). Yet when I asked her, why dun u come over, her reply was she’s lazy. ARGH.
