Family 1: Being a Parent: Was it a Wasp? Calling Mum ... A tantalising half-a-tale of a long ago Freshers' Week overheard on a bus by Elizabeth Obadina

A phone rang. 
A lady with salt and vinegar hair, wearing steel rim glasses and a white hoodie answered,"

“Well if it stung you put vinegar on it.
It’s alright …
No … I should be home about half three.
Where’s it’s swelling?
You need to know what it is.
Only put vinegar on for a wasp.
Yeah … it’s amazing how much it hurts!
Sounds a lot like a wasp.
Doesn’t look like a wasp?
Where was it?
Oh! That wasn’t very nice of it …
Are you on your own now?
Oh, it’s freshers’ week now is it?
You’re on your own now?
No …
If it keeps on getting bigger then you’d better get to a chemist to check that it’s nothing else.
Aah uh … (laughs gently)
Maybe she can fix it for you?
You’re hoping are you?
It sounds like it.
They don’t last forever…”

And on that ambiguous note, the lady on the bus snapped her phone cover shut, rang the stop bell and got off leaving her fellow passengers agog for answers: Who was the companion? Where was the sting? Was it a wasp or something much worse? AND What doesn't last forever? The sting? The companion? Freshers' Week? Life?
