If you need to leave the dinner table what do you say

The most common and polite way to leave the table is to use the expression, "may i be excused?" make sure to give them a valid reason for leaving, such as " aliens have just landed in the backyard" and making a getaway for the tv or "SOMEONES BREAKING IN" and dumping whatever you dont want to eat on your distracted sibling or parents plate .

so what i did was i used google translate and this is what i got. where do you live? what do you do in your free time? what kind of music, food, sports do you like? what is your favorite color? who is your favorite artist? so what they are doing is asking u questions about urself and u have to respond in spanish or english i bealive. hope this : )
