You should never give a boss a birthday card, because they will think wrong of you by saying you are not worthy of the job or that you don't take things seriously.
Anyways you are not going to work to celebrate someone birthday you are going to work to earn money, which is hard work
An appropriate gift for your boss is sometimes a tough decision. A gift card to someplace you know your boss frequently eats or shops is appropriate. Also, something related to your field of work. For example, if you work at a bank you could give you boss a nice pen with his or her name on it.
Zazzle.com has wide variety of birthday cards. Depending on your boss's sense of humor, some of these cards will really give him/her a laugh but on the other hand, I would stay away from some of them.
An Office Depot or Staples gift Card.
Why would you give him or her anything? Just because an employee dies is no reason to give the boss something. If they were relatied somehow, a card would be all that is required or should be expected.
On someone's birthday.
Get him a nice brotherly card:)
A classic card to give for a birthday would be the classic happy birthday card.Other classic cards to give to one for their birthday would be a happy birthday and a hope for more to come.
I think that you should if the teacher is a girl. If it is a boy, than maybe a check or a gift-card. :)
write a birthday card and give it to them :)
only, if you're still friends otherwise why does he deserve it?
I do not believe that you need to do more. Their your ex, so you can now treat them like you would treat anyone else that you would give a card to on there birthday.
Valentine's Day is for lovers to give one another a card and maybe a gift etc, but it's not for children to do anything for their parents. That'd be like giving someone a birthday card when it's someone else's birthday. But of course, if you want to, you can!
