Was I wrong to change a form of authority emailed to me by my solicitor before printing it out

[HecatesTwopenceworth]

signing it and sending it back?

from I, Hecatestwopenceworth, hereby gives permission....
to
..hereby give permission

???

because if someone else was talking about me, they'd say she gives permission, but I wouldn't say about myself that I gives permission, I would say I GIVE permission.

You don't think I'm just going to piss off my solicitor?

Only if you'd amended it in red pen and written "tsk" in the margin!

It would be very satisfying, wouldn't it?!

Maybe he's from the West Country and does actually say 'I gives it' (that only works if you adopt a very strong Vicky Pollard accent, though) .
