AIBU or is she?

[HtotheS]

My mum doesn't work so is at home all week. A friend of mine cancelled so I rang my mum this morning and asked if I could go to hers for a couple of hours. She hasn't seen my daughter who's 15months for at least a month now, I thought she'd be pleased.

Instead she said she had lots of eBay parcels to get ready!!!

I was only going over for 2 hours max!

Is she being unreasonble or am I ?

If she's sold stuff on Ebay she has committed to posting the items with a set time, so it's exactly like any other work - she's busy.
I see my parents every few weeks, and sometimes call them when plans fall through - often they are delighted, but sometimes they have plans and can't. Way of the world.
YABU.

I agree that of she's busy then she is not BU. Can you visit at the weekend?
