What would you say?

Mind the hydrangeas.

Please don't park outside my garage door.

As the Queen (allegedly) asks “Have you come far?”

Have you come from afar?

Don't be bringing your germs here !

My!! you looks as if you have had a long journey, come in and your welcome to use the facilities.

I hope your spaceship hasn't damaged the lawn.

What kept you?

You look tired are you suffering from jet-lag ?

Are there mire on the way ?

DO YOU SPEAK ENGLISH?

How do you fill your days? Read any good books lately?
My attempt to find out if there is intelligent life out there.

If Sci-Fi films have taught me anything kitty of course they will speak English, with an American accent.

I somehow knew you were coming! I’ve been sculpting my mashed potato for weeks now!

Please may I have a go driving your spaceship?

Welcome, are you here for the Brexit talks?

bImatlhba' Hop?

just to see if they speak Kilngon.

"Welcome!

Please don't leave your deposits on the pavement, maybe that's what you do on your planet, but it's not okay here, if anyone steps in that slime, they are likely to go base over apex and break their neck, and yeah unfortunately human necks are a bit inflexible in that they don't have that bendy twisty quality that yours have. Maybe in time we can develop the adaptations that you all have but that may well take thousands of years, so in the meantime try keeping your emissions to the designated areas that will be set up for such purposes. Many thanks for your cooperation in this matter and have a nice day

LOL....some very funny answers. I was trying to think what I would say to anyone who landed in my garden unexpectedly......probably OMG....are you alright?

Klingon!

'Don't let the cats out!'

We have indoor cats and they get terrified if they go out.
