Yeah get some lines ready to trot out when you get asked things. Learn it’s ok to say No. At first it’s easier with an excuse but you need to get to the stage you don’t need an excuse.
Eg. Friend asks ‘
Can you walk my dog on Tuesday as I’m on a double shift’
You:
I would always help if I could, you know that, but unfortunately I can’t this week, sorry friend. (Then change subject so she doesn’t push, like ‘Talking of walks, I’ve seen some nice trainers online I’m thinking of buying‘. That way the subject has been changed and she should respect that).
Other neutral comments to use when people tell you stuff they expect you to volunteer to help them with but you don’t want to but also aren’t good at saying no.
‘Oh no, I’m sorry to hear that’s happened, that sucks’
‘That’s lousy friend, I hate when that happens to me’
‘I wish I could help but I can’t sorry, I hope you get it sorted’
