I need help surprising my boyfriend!!

Sophie

So my boyfriend is working away down south ( like 6 hours away from me ) at the minute and I’m not going to see him until Sunday.

His parents are travelling down on Friday afternoon to stay with him and bring him back on the Sunday, both his parents and him asked me if I wanted to go too but I said no.

So he thinks I’m not going.

But i’ve text his mum to ask if it’s still alright to go with them to surprise him.

He’s got my location and it’ll obviously take around 6 hours to get there and I don’t want him to be able to track me so was just gonna put my phone on airplane mode so he couldn’t track me. But whats a good excuse for my “phone being off” for that amount of time without him getting mad?

Help!?!?!?
