Mum going out with men

Hi OP,
If this is worrying you definitely have a chat with a friend about it. You could tell your dad, as this the morally correct thing to do and it is very suspicious behaviour from your mum - however you need to ensure your mum will not turn what you've saw back on you or claim your lying? Maybe take a date stamped photo and send it to your dad so there is proof. If there is nothing to it then she will be able to explain herself.
stay safe OP, hope it all works out

What does your mother do for a living?
She may be working the night shift and getting lifts from her employer or coworkers.

I can't tell from your post whether this is a regular occurrence or a one off. What reason did she give your dad/your family for being out?

I'll report it then

what do you mean you'll report it? How old are you

This seems like yet more bullcrap

She can go out with whoever she wants to.

I think you’re making quite a few assumptions here. Where was your dad in all of this? Surely he knows about it already?

I might be but it does seem weird and he knows but I don't know what he thinks
