Remember The Sims? I only ever played the first of The Sims games, so I'm not sure how different it is now. But I remember that the way Sims would make friends (or not) was by walking up to complete strangers and talking to them about whatever was on their mind. If they liked the same things (tennis racket, judge's wig, video game) they became friends. If not, they did't.
One of the easiest way to make friends in Latin, then, must be mihi placet - it pleases me. Throw on an infinite verb and you have just declared one of your favourite things to do. mihi placet in horto ambulare - It pleases me to walk in the garden.
This picture was painted by Marcellus.* It pleases Marcellus to paint.
*It wasn't. Again, I don't know who made this, but I think its awesome.
