Dropped S off and instead of instantly saying bye I let W initiate conversation. Need to to better at this in the future but anyway.
If she wants to talk that's fine, just limit your responses to validation comments.

Me: I better get going
Good.

W: what’re you gonna do? Me: probably go on a motorcycle ride
Next time- "I have some plans, need to get going." If her responses are that disrespectful then she doesn't deserve to know what your plans are.

W: (mocking tone) ohhh I’m so cool, I have a motorcycle, I’m a doucheb*g. Me: Watch your mouth. Don’t talk to me like that.
Right idea but wrong attitude. Don't let her drag you down to her level.
Quote
W: (still mocking) ohhh did I hurt your feelings. Me: no but you are being incredibly disrespectful. Goodbye.
THAT is the right attitude. Perfect.

She kept going trying to draw me back but I left.
Great!

Hour later she texts me picture of S and “S wants to show you his new backpack”. I haven’t responded.
On the off chance that your S really did want to show it to you, I would not ignore messages about S. Reply back with a response to him such as "Tell S I think that backpack looks awesome."
