Help me see the funny side??

[SweetPea90]

So not to drip feed me and DP have a DD 4months and DSD 14yo.
We go out tonight, us 4 and DP brothers family. My dad tags along.
My mum meets us after work - she's not drinking.
We all have a good time, laughing and enjoying the sun!
My parents leave, I then get a message from DM "your DD is on Facebook with 3 drunken men for everyone to see"
I am baffled, literally! Last picture taken was of my DP and our DD by me by a lorry (DP loves them) and then his mates were taking the piss of him so asked me to take more pictures as a joke of them by his mates car!
So my DP just posted them all to Facebook.
My DM has taken offence for some reason. I tried to tell her all the pictures were in jest. The last message I got was "I guess we find different things funny"
AIBU to think F off!!!!

So are there pictures of your DD & drunken men?

No my DP, his bro and best mate asked me to take a picture of them taking the piss out of DP and my DD was in the corner of the picture. No1 was drunk, it was all a joke.
They were all taking the P out of DP because he loves lorries!

I don't understand... can you explain more clearly OP?

Sorry cross post. So they're just messing about by a car?

Basically, I've taken photos of my DP and his mates around a lorry and a car. My DD happens to be in a few of them. The guys are being very OTT in them as they are taking the piss out of my DP. As a joke.
My DM seems to have taken offence by them purely because my DD happens to be in a few of them. It was all very light hearted.
She seems to be making out that we aren't responsible parents through the messages we have received.

My DP was having a joke which I was very clearly involved in, neither of us was drunk. But my DM seems to want to paint my DP in a bad light.
I just can't see what she wants to achieve, apart from pushing me away.

Your Mum refers to her GD as "your daughter" rather than our Ellie (had to call her something). It sounds very detached me

Sounds like your Mum is BU. Not you!

How were they “taking they piss” about him liking lorries?

She refers to her as 'your daughter' and also refers to the 'drunk men', but she's with her Dad in the photos.

She's ridiculous.
