Just say "hello Mr/Ms______".
If your parents never met that teacher, you can make a quick introduction... "Mom/Dad, this is Mr/Ms______ he/she teaches Spanish/biology/whatever in my school. Mr/Ms______ this is my mother/father."
If neither of you seem to be in a hurry, do some small talk (nice to meet you, the weather is beautiful today, they sell wonderful strawberries here, e.t.c.) Wish them a good day. End Of situation.
You can either act like a rude person and give the teacher incentive to talk to your parents in public by ignoring them or you can be polite and make a quick encounter.
For me, my old Biology teacher comes to my gym and works out. I always say hi or stop by to wave and he does the same. We keep it short and simple because we both came to work out and not chit chat.
What other thing can you do other than say hello and talk a little?
If they see you well just say hey, if you don't want to because you are going to get in trouble because of something you did, then time to stop it.
If your ashamed, get over it, those are simple things that people don't think anathing of.
when ever i see my teachers outside of school i just act like i dont know them unless they say hi to me. if they dont i will not acknowledge them either.
unless the teacher is your friend then u can say hi.
smile, nod, wave, say hello. or just keep walking depending if you like the teahcer or if you hate or stronly dislike the teacher... although saying hi may get you some brownie points!
haha i remember those days, i used coax my parents a differnt direction so my teacher didn't see me haha
Just say hi and keep walking... don't want him/her to start talking to your parents!
ignore them cause they never shuddup when your parents talk to them o_o
smile...wave...go about your business, unless its a cool teacher.
Just wave & say, "Hey Ms/Mr ______". Easy enough, haha.
run away screaming "AAAAAGGHH!!! MONSTER!!" haha
LOL! This made my day =)
Just say hello
