to not want to do this?

[stillloveholly]

both mine and friends ds go to an after school activity but it finishes at 9.30pm. friend lives 2miles out of my way but has asked if i will pick up her ds and drop him home-not sure why she cant do it as other parents come on foot/bikes/with babies ect.
dm and dsil think i should refuse or only offer once in a while but not sure if being unreasonable or not

Do it if it suits you to do a friend a favour, if your ds would like you to and your friend will reciprocate when you need a favour, don't do it if you will resent it. Let your dm and dsil mind their own....
