Some people find it very difficult to ask for things. Asking requires that we admit we need something and we can feel that it gives an advantage to the person we are asking.
We can sometimes think that asking is equivalent to begging. We will in that case try to manipulate others into giving us what we want or act as if it is of no importance or we will try to take it just to prove how strong we are.
When we do that and we don't get what we want we can feel vindictive and seek to find ways to pay them back. A lose- lose situation in all cases involving relationships.
When we have developed good relationships where we have mutual respect then asking is not presuming on the relationship it is simply recognizing that very little in life can get done without others.
Asking is the gateway to cooperation and reciprocation when the need is reversed. Asking is not a weakness as is perceived by many but an acknowledgement that we are not perfect. The human condition.
