Is 'excuse me' the same sign as 'forgive'?
Yes, they use the same basic handshape and movement! However, 'forgive' is often signed with a larger, more deliberate double-brushing motion, while 'excuse me' is usually a quick, single or double brush.
How do I use this sign to get someone's attention?
If the person is looking at you, simply sign 'excuse me.' If they are looking away, gently tap them on the shoulder first, then sign 'excuse me' once they turn to look at you.
Does it matter which hand does the brushing?
Yes. Your dominant hand should always be the one doing the brushing motion, while your non-dominant hand acts as the stationary base.
